Lzvxtym 2Pcs Multifunctional PH Meter TDS EC LCD Water Purity PPM Filter Hydroponic Pool Tester Tool

Well worth the low price. They work as they should. The only downside is that the readings bounce between 3 numbers which is fine for plants but wouldn't be good if you need a solid number.

works well with no problems. I just wish it was water proof. I dropped it in water twice.I opened up where the batteries are and left it overnight and when it dried went back to working properly

Easy to use and seems accurate.

I was very satisfied! I forgot to order batteries but to my surprise they even came with them. they work great!!!

amazing so far has not given any off problems or anything, seems to be accurate

I like the quick reading, lcd screen, and handheld pen style of this product.

Very easy to use. It's kinda big but that's good bcuz it doesn't feel so flimsy or breakable.

PH pen was iffy but other than that product was okay

Needed for a school project. Good price for both

One time an old timer said to me....."If you buy something quality, you usually never have to buy another item like it again". He was right. I'm not going to bash the seller because it is what it is..... something made cheaply for folks who can't afford something more expensive that actually does what it said it does. It doesn't do the job very well or accurately, it may not look as streamlined or pretty. It may not work very long or wear out quickly. BUT...... when you make it look like it does and it isn't accurate and has a rating that could not be true based on these two items miserable performance that can't be trusted at all, thats a scam.
