Sept 11, 2018 I purchased buy two get one free air coolers from Exclusive Deal shop. It took all of the three weeks for delivery. My initial use of two of the coolers immediately failed when I inserted the usb cord into the cooler receptacle. The receptacle for the plug receded into the machine which prevented the plug from seating resulting in no electrical power to the unit. I immediately emailed customer service (within the ten day window) and received a response and assigned a request number, 16827 on Sept 12. Well, thats the last time i have heard from them. I have sent subsequent emails to no avail. This company is beyond reproach. I spent $177.00 for 1 of 3 units that work.. Very defective product...Do not buy if you expect any resolutions to any issues you may or will have. Very DISSAPOINTING PRODUCT AND COMPANY!
