Just gave it 4 stars b/c one showed up broken even after I replaced the battery. Otherwise easy to use and change batteries. :)

I have been completely mislead.These are beyond small and if you choose to have them working when you have company over prepare your self to be wasting ample time for turning the little and I mean tiny balls on. I have no idea how long the life is for them plus what I would have to purchase to get them to light up again. I have been literally fooled and I am truly a daily amazon prime customer.Sad and madI am asking you NOW BEFORE THE DEADLINE FOR RETURNS WOULD THE COMPANY WHO IS SELLING THIS…

So diaspointed, we tightened all the bottoms before throwing them in the pool, dried them and out them in our house until the next use. Dried out in the house the next time 18 out of the 20 I bought are no longer working and insides all rusted after 2 proper uses!Super cool light balls NOT waterproof
