Was hoping this version would be better, but no. Welcome to the Nite Ize repair center. The pictures show the old version run by LED batteries. Although they claim the balls are waterproof, no. I’ve learned to clean out the contacts and add new batteries to reuse them, but a lot of the time the rust has already formed. The new rechargeable version is more expensive and has the same ‘waterproof’ casing. First charge was good; second charge didn’t even last for our retrieving sessions one evening. Third session on a full Charge didn’t even last one session. Too much money for the quality. When they work - they are great. Unfortunately, still the best on the market, it it’s just like throwing away money. Innovators???
