A necessity for maintaining proper pH values in water.
This item is necessary to maintain proper pH levels in the water. This water is utilized for feeding the plants which are highly sensitive to high pH values. I have actually recommended this item for purchase to another individual and he to agrees that this is a very good product.

Handy little ph meter
So I finally got one of these little digital pens to check my water and honestly it has made me feel like a total scientist in my own kitchen. I used to just stare at the tap and wonder if everything was okay but now I can just dip this in and see the numbers pop up right away 💧 It is basically like having a tiny expert living in your drawer who tells you exactly what is going on with your drinks so you dont have to guess anymore. I was actually suprised by how fast it works because I thought it would take ages to get a reading but it is usually done before I can even finish humming a little tune. It is super light and thin too which is great because it doesn't take up any space at all and I can even take it with me when I go to visit my parents 🏠 You just pop the cap off and stick it in the glass and then boom you have all the info you need right there on the screen. I accidentally left the cap off for a few hours once and I was worried I broke it but I just rinsed it off and it kept on working like a total champ. The best part is that the screen is really bright so I can even use it in the morning when I am still half asleep and havent turned all the lights on yet ☀️ I basically just point and click and it handles all the complicated math for me which is perfect since I am definitely not a fan of doing science experiments before I have had my coffee. It fits right in my pocket too so I can even use it to check the water at the gym or when I am out on a long walk in the park. If you are someone who likes to know exactly what is going on with your hydration then this is basically a little dream come true 🥤 Just make sure you keep the sensor clean or you might get some funny readings that make you tilt your head in confusion. I am honestly thinking about getting one for my friend who has a huge aquarium because it is so much easier than those messy drop kits with all the different colors. It is just a fun little tool that makes my daily life feel a lot more organized and I think you would really enjoy how simple it makes everything feel 🌟 It is basically like a magic wand for your water glass which is pretty cool if you think about it. I am very happy with it and I think it is going to stay right next to my favorite mugs for a very long time.

Recommend for students that need it for schoolwork
Definitely think it should have arrived with more solution calibration packets. I feel it was a little difficult to use at times. The meter would simply turn off after a while. It would do it even while using it to test the ph of a solution. Made it a little more time consuming to have to turn it back on and recalibrate it. It is fairly small which makes it easy to store. Purchased it to do schoolwork for a chemistry class. When comparing my results to the ones of my teacher, I would say the ph tester is accurate. It works well for the price and amount of chemicals I dipped it into.

Useless, it's now in the garbage getting inaccurate pH readings of my trash
Calibrated it per the instructions which stated I only needed to do the 6.86 pH test per if only .1 plus or minus accuracy is needed, versus plus or minus .01 accuracy, in which case you should calibrate it using all 3 pH powder packets (6.86, 4.00 and 9.18). Rinsed sensors with distilled water and let dry. Then I tested the accuracy with distilled water, which should be around a 7 neutral pH. The thing just started in the high sixes and just continually counted down slowly to the 5.XX, then 4.XX, then 3.XX, etc., never once settling on a pH. Would've kept going but I removed it from the distilled water. Then I pulled the batteries to reset it and decided to test it again with all 3 pH packets. Did the 6.86 fine. Rinsed with distilled water and let dry. Moved on to the 4.00. Calibrated fine. Rinsed and let dry. When I tried to calibrate for 9.18, the meter went in the high 8's and I held the calibrate button for 5 seconds per the instructions ("when the reading is close to 9.18, press the CAL button for 5 seconds). Did that and the screen then showed that it had been calibrated for 6.86 rather than 9.18, which obviously completely ruins the purpose of a calibration test and throws the calibrations all out of whack. That's when I threw it away. I guess you get what you pay for. In this case I paid 12 bucks for an hour of wasted time and a pH meter that doesn't work at all, even when you are trying to calibrate it per the manufacturer's specifications.

She works
I was surprised at the price but curious as I am used to paying a bunch for blue labs. The fact that it worked great and was accurate makes me wanna buy a few more just to have them Incase I ever need to double check my ph or if a friend needs one. Update: Product started to not read pH correctly and as I looked at the bulb, it was broken. I did not bang it on anything or do anything to it to causes issue but it broke. I’ve had labs in the past and I realize this is a vape brand ph meter But I don’t understand how the bulb would’ve broke. For the first few readings at read perfect. I’m not sure what happened

Very useless device. Does not provide a stable reading. I can’t even calibrate it because it just keeps going up and down non-stop. Fluctuates almost 2pH up and down. Highly recommend not buying this.
