    No listed phone number for customer support?? They did eventually call me, from a personal phone- and I get it- you’re small. BUT STILL- hire people to answer the phones like amazon. I don’t want to email. I just needed to know how to change my login and not gonna wait 2 hours for an email.

    Awesome customer service- I’m a Canadian citizen who recently ordered the tCheck and expansion kit. I ran into a few issues with Customs and after only a few email, the person with whom I dealt at tCheck was able to resolve my problem and left me a very satisfied customer. I haven’t had a chance to use my tester yet, but I am very much looking forward to knowing exactly what the THC level is of my almond butter “budders” rather than playing fast and loose as has happened in the past! Thank you to tCheck for making a product that doesn’t require a science degree to operate!

    I am on a fixed income and watch every dollar. So I had a lot of questions and concerns. Their support staff helped me through any and every question I had. They got their answers to me fast. While never making me feel rushed. The only question left unanswered is what should I test first. Thank you.

    Prepare your samples and you will be good to go, I will say, this works fairly well if you are careful. You have to make sure you homogenize your sample, and if you dilute- use a scale. If you aren’t familiar with best practices for precision, you can easily mess up. The device is a spectrometer, so obviously if you block the UV light, it will detect something. That isn’t the machine messing up, that is simply how it works. I have worked with HPLC in the past, so I know how to prepare samples, but I think for many people, if they aren’t accurate- the results might not be as well. Testing dried cannabis is similar actually, but again, you have to accurately weigh and measure the alcohol to get an accurate result. I’ve compared a few results to HPLC results at the lab in my state, and I’ve been pleasantly surprised at the accuracy.

    This is a must have if you are making edibles or dosing for medical reasons. I purchased it to obtain CBD strengths and it works like a charm. Now there is no guess work involved.The customer service is also a big plus for information and guidence. I would recommend this device to any home grower or for checking purchased products

    Customer service to the rescue: Had a bit of difficulty figuring out how to use the tcheck app but their staff is really responsive and walked me through the process. Thanks Lisa!

    Great service, great product-I have been enjoying my TCheck2 since Spring 2019 and it has been a game changer. It is nice to know the strength of my edibles before I unleash them on the world.The TCheck2 team are great at answering any questions and always get back to me within 24 hours. I can hardly wait to see the advances they make for measuring flower-infused EVOO, my favourite infusion by far. If you want to be sure of the potency of what you’re cooking up at home, the TCheck2 is a must.

    This is the only way I can test for how strong it is, and make sure I’m not taking too much or too little. I am a medical patient- and in my area, there are no labs. It was a really big purchase for me, so I’m really glad it works. I left my tray in the sink- and accidentally got it in the garbage disposal- and they said I had to send it back for a new tray to match with it- and they got it back to me real fast – which was good because I make small batches 2 times a week so its fresh. Just make sure you filter really well before you test! Any solids or bubles are bad for good test results.

    I don’t trust store edibles, even with “lab” reports. We all know companies can lie and pay for results they want. I’m growing my own now that I can, and this was sort of just a fun perchase to play around. We have a little contest going of who can grow the strongest- indoor vs. outdoor. Still a fan of the old fashioined method of testing by rollin one up. Good machine though.

    Proper Dosing is important. We test all our products in house with the TCheck2 💚

    Great device. Tests concentrates, buds, and edibles. It’s a win win.

    Ok- so if you are making really strong infusions, this might not be the device for you. Given, there aren’t really any other options, and it is the most affordable by far- but you will need to dilute your sample before you test if it is really strong. That is the only downside I have so far. I’ve been using it for about 8 months. Just got the Expansion Kit for Flower and Concentrate. I haven’t used it yet- but I’m excited to try it out as well!

    As a grower, it’s nice to be able to prove to people how strong it is, right then and there. I would love to get terp levels, on at least a few but I don’t think it can work that way. Next season I am going to start some hemp strains, and it’s nice to be able to test them. They mentioned they are working on a way to share results, which I requested- but for now I brag via screenshots 😉

    I enjoy testing my buds. This machine helps me know what my batch potency will be before I send it to the lab. That way I dont burn money on batches that dont pass. Thanks!

    Happy Chef 😁 I am very happy to be able to measure the mg/ml potency of my infusions and that is working well. I can’t wait to start testing my buds!

    Very accurate. I was always interested in these machines but I also had my doubts as to the accuracy. Not so sure a unit like this would be that accurate. I borrowed my friend’s tcheck and ran a test on an infusion I also sent off to the lab. The results were spot on!

    Once I figured out how to dilute it and then multipy it- it made more sense. so at first I thought it was bunk because everything said 15mg/ml but it was actually saying more than 15ml/ml. I had to re-read the direfctions a few times. Customer service was pretty nice to me- even though I was not, but I said sorry once I realized it was an “over” reading and not a broken tester. I wish there was more help in the app, that’s my only suggestion

    Service and Product Excellence: I had to return my TCheck for recalibration and a new trays as I had managed to get a a couple of cracks in the original tray. From sending my machine to having it back to me—in Canada, no less—was a mere 10 days.

    Can I give 10 stars? I bought this off a different site- and their customer support sucked. SO I emailed t-check direct and they were so helpful! They explained a lot, and sent me links to read up. There was so much I didn’t know. There is also so much out there that isn’t based on science at all, so it’s a bit annoying now that I do know more, because so many people don’t and act like they do. Honestly- even if my tcheck didn’t work- I’d still be happy they took the time to teach me as much as they did about why edibles feel stronger, and how to decarb the right way and so so much more. They went kinda above and beyond with that.

    Very happy with gen 2, I can’t name the company I work for, but we have been using tCheck in house for years. The original one was a bit limited, and I love the new one. We always test before we send out to the lab. I know it’s saved us a ton of money due to the fact that we don’t need to reformulate multiple times anymore. You would think after so many batches, numbers would be pretty much the same, but there are so many variables season to season. It would be great if we could get all the results shared in one spot though, as we have 3 of them we use, but that would be a feature I would like to see.

    Keep up the good work. Customer experience is GREAT! Other companies could take a lesson from TCheck for how to treat customers before, during and especially after the sale. Other companies I’ve dealt with get amnesia after the transaction, not TCheck! Keep up the great work and be the benchmark for others to follow.

    I know it’s not their choice…But I am not having my location on for testing. Nope. I keep my phone off and untraceable and never use google either. If they made one that didn’t use a phone to show results- I would use it but I can’t have any of this app stuff.

    Just got this as a birthday gift. It took me a while to figure out how to use tCheck. When making caramels I discovered that I need to measure the infused butter before adding sugar and cream.

    Helps me get top dollar! Knowing the potency of my different strains upfront helps me maximize the return from all of my hard work!

    With all thats going on in the world right now…Now seemed like the best time to start testing our infusions so we can stay level headed throughout the day without over doing it. Its pretty easy to run multiple tests in a day.

    I had to return mine, because it doesn’t test below .03% for hemp. Wish there was an option for us, but nothing seems to be affordable for hemp farmers to test. They said they are trying to figure out a solution for us, so I’ll hope for that. I’ll give it 3 stars since it didn’t do what I needed- but they let me return it even though I used it and it did what it advertises. Just tired of spending so much on testing

    Happy testing! The process with flower and concretes is very straightforward. It seems daunting at first but after a few tries it’s fun and kind of addictive. I’ve tested everything I have laying around.

    It’s a pretty good device to have on hand. I bought it shortly after buying a Magical Butter. The two together have improved my edibles game.

    Im not going to lie it was alittle bit of a bumpy ride. I was sent the wrong colour but thanks to Lucky at tCheck they completely acknowledged the error and did everything in there power to fix the situation. Great customer service. Tcheck device is of amazing quality and would strongly recommend for anybody serious about dosing as close as possible without paying a lab every time.

What is winterization?

Winterization is a refinement process where waxes, lipids, and chlorophyll are removed. tCheck is unable to directly measure these other non-cannabinoid plant compounds and some may affect tCheck’s sensor.

Measurements for infusions based on plant and non-winterized concentrates are calibrated, but not to a reference standard. These measurements assume a certain amount of other compounds and are adjusted accordingly.
