Small Floating Dispenser with 50 Multifunctional Chlorine Tablets, Swimming Pool Spa Instant Cleaner for Hot Tub, Sets with 50 pH Testing Strips, Measures PH, Alkaline and Chlorine

Very good

Very poor product. Tablets are not slow release as needed in the floater. They dissolve in 5 minutes. No instruction. No safety guidence. No contents. Dont even smell of chlorine- they could be anything.I would rather bin them than risk putting in my spa.Test strips show colours that arnt even on the chart and dont detect any chlorine if you dissolve the tablets in a cup.Floater is usable but very thin and lid doesnt lock properly.I have complained strongly and asked for refund but no responce.I should have read the reviews.Dangerous- Not complient with health and safety.
