Love this
This takes the guessing out of trying to read test strips that don’t seem to be all that reliable. I was tired of trying to read different brands of test strips done at the same time that were giving me different results. With the cost we spent on purchasing a heater for our pool, and being told our heater would be ruined in a matter of 6-12 months if the chemical balance wasn’t done properly, I decided to spent the extra money on this. Makes everything easier and is much more accurate. I really wish it came with the extender, you aren’t able to take readings from inside of the house, you have to be standing right next to the pool to get a reading. I’ve also read that battery replacement is expensive on a yearly or bi yearly basis. If you have a pool without a heater and don’t want to spend the extra money, test strips will be easy enough. If you have a heater and need the balance to be perfect, or are trying to run a hot tub this is well worth the money. Will more than likely be buying another one eventually for the hot tub.
