Bought this because I was tired of trying to figure out the colors in the test tubes. It works great, but does not work per the instructions. Called the maker's toll free number and had to leave name and return number. Been a week now and still waiting for them to call me back. No way to calibrate so you have to trust them that it is accurate.

If you have a difficult time deciphering the test strips, or comparing the colors in the test kits to try to determine the levels of chemicals in your pool, then you have found the answer. This product is a God send!!! It takes all of the guess work out of testing water.

It is so easy to use and understand. Takes the guess work out of keeping the pool balanced. I don't have to travel to the local pool store to get my pool water checked.

WOW! FINALLY SOMETHING THAT CAN GIVE YOU A REALLY GOOD IDEA OF WHERE YOUR IMPORTANT POOL READING LEVELS ARE. WHAT A BREEZE, TURN IT ON, DIP THE STRIP, LAY IT IN THE CHANNEL, AND NUMBERS APPEAR ON THE SCREEN. HOW COOL IS THAT? NO MORE COLOR MATCHING AND TRYING TO DECIDE, IS THE PH LEVEL ALRIGHT? WHAT'S THE ALKALINITY REALLY AT? IS THE CHLORINE AMOUNT OK? WISH I HAD THIS 2 YEARS AGO!!

Finally a product that takes the guesswork out of pool readings. I wouldn't trade this machine for anything. The only caution is to make sure you wipe down the strip reader after your test is completed. Trace particles of the previous test "may" alter your next reading

This takes the guess work out of reading the strips which I always had a problem with. There is some difference between this and the srips but It gets you close I love it

Easy to use and is right on at times with test kit and strips, but at other times readings are questionably off. I rated it 3 stars due to inconsistency.

This is a MUST HAVE item, if your like me and either A.) Need glasses or B.) Are tired of guessing? The Digital Reader is a great stocking gift, and I can't count how many test strips I have wasted, my digital reader takes all the guessing out and I get better readings then the local pool store.

I cant stand guessing the readings on the strips or liquid test kits!! This digital reader is a life saver. I never have to guess again. I just put the strip in the pool, then into the reader, and it tells me what chemicals I need to add!!

I have had my AquaCheck for two weeks now and use it frequently as I just opened the pool. It is easy to use and fast however, I found accuracy to be a problem. I have done back to back tests on three separate occasions and have found a 10% to 15% difference in readings. Bottom line I still have to go to the pool store if I want to be sure.
