I used test strips and a cheap tester I bought somewhere else and could not get my test numbers to ever be accurate. The water my hot tub had so much of a smell when you turned the jets on that it would choke you and you couldn't even sit in it. From everything I read, this was due to incorrect readings I was getting from test strips. I ordered this kit that was recommended and have not had the smell problem anymore.

Be careful when you purchase this item. The version I was shipped had expired chemicals, so it was worthless. I suspect the product is fine, if the chemicals aren't all too old to use. I would ask the vendor to check the expiration date of the bottles inside the kit before you purchase.
