Great ! Even brought a spare as they work so well. Very accurate and easy to use. No need to spend a fortune, perfect at this price.

7 months it lasted, I needed to change my batteries-no biggy. Apart from it won't display any digits except 0.0000 and the temperature. It won't let me calibrate. I know it's only £20, but how many do you need to go through before you find something that's decent?

Went faulty after two months use requires a new probe

Great price and works well!!

HANDS DOWN THE BEST PH METER I HAVE EVER OWNED. I have tried several, you might need to buy liquid ph solution to calibrate properly BUT once it is calibrated this baby GOES. From a hydroponic grower who is serious about accuracy, you can’t go wrong. I plan on ordering a back up as well. :)

Great little meter. The solution stays good well over 15 days. It will give super accurate results if you calibrate with all 3 solutions, but since I only need +/-.1 accuracy, a once or twice daily calibration (which takes 15 seconds) if sufficient for me.

Easy too use really like it

Saves me time and was accurate out of the box
