Got a indoor, and outdoor pair. I have 25-30 pairs of fitflops and theyre just as comfortable as all the others. Though the battery doesnt allow many hours of playtime. This shoe box met my needs well. My 2nd pair of fit flops, will no doubt order more. I lobe that it is super soft and I had older slippers,but they were worn out. Great quality and looked better than we expected. Its waterproof, IP67, and dustproof. LOL. Overall Im super satisfied.
