Great product, but needs to be tied off with fishing line rather than the string provided

Really, what more could you want? It’s large and easy to read temp is terrific for my ahem 50+ eyes. Sometimes it doesn’t submerge, but floats almost straight, which is an problem because when it floats on it’s side, the temp is several degrees warmer on the surface. I suggest you put a small counterweight on the bottom, after you buy it. I further suggest the company add a permanent heavy tip to the product. Would have given this 5-stars except for the cheap string provided to tie the thermometer to the pool and the weighting Issue mentioned previously.
