Review on Stay Cool and Hands-Free with the Tikduck Neck Portable Sports Fans: USB Rechargeable Desk Fan - Black by Mike Vargas

Bought this for my wife because she always works hard at her work and heat is exhausted. She likes how powerful the fans are and has decent battery life depending on what speed you set it to. Unfortunately, this product has a shelf life of 1-2 months. I swapped it and it doesn't work again! First one fan stopped responding so I took out the warranty and got a replacement, then it happened again with the replacement. The motors seem to have stalled because I was tapping on them and trying to manually rotate the blades to get them running, but they didn't respond at all. This is a great product but the lifespan is very short. Your heart is broken before long because they are VERY effective when they work properly.
