Product review
Great product worked as expected and advertise. It has been a year now and it still works like it did brand new. I didn’t even have to calibrate it.

Quality Product!
Just what I needed. Includes everything to set up and calibrate the unit.

Chinese garbage
I would not recommend this pen to anyone. I calibrated this pen along side my Apera. This was off significantly, to the extent it is worthless. Good luck with customer support from China. Just buy a decent pen from Bluelab, Apera, or even Vivosun.

Works well but takes a bit of time to settle out
Another Update: I reached out and they sent a replacement for it right away. Great customer service! UPDATE AFTER 2 MONTHS: had to knock this down to two stars after the pH sensor bulb decided to fall out and then broke, rendering it useless. I'm outside the return window and will have to order another sensor. Worked great up until its self destruction. I'll be reaching out to YINMIK to see what kind of support they can offer. ORIGINAL REVIEW: I've been using this thing everyday for about 3 weeks for a hydroponic grow of veggies and leafy greens. I calibrated it when it arrived and again last night. it had only drifted about .04 which is negligible so it seem to be holding its calibration (for an admittedly short test run). I find that if you are moving from one solution to another and they are different temperatures, it takes extra time to get a stable reading. just be patient.

Great tool for the money
Excellent little device. Much less pricey than the older unit I replaced. After a year it's still going strong. Keep the tip clean to avoid mold dirt etc. That is the only issue.

Must have for greenhouse Reservoir
Been running this for about a month now calibration is holding well and love to be able to check my temp pH and EC from my phone

Though I never tried the super high end EC meters for 4x this guy's price, it's super accurate and has been since I bought it a few months back. I tested it against 2 different name brand drops. Just take care of it and rinse it off with distilled water every time you use it and don't smash it around like a toy and nothing will break or malfunction. Love it.
