Cy-Fi Wireless Bluetooth Sports Speaker - Portable Waterproof Outdoor Speaker for Beach, Pool, Gym, Hiking & Camping (Red)

(See update below)I purchased the Bluetooth version of the Cy-Fi Wireless Sports Speaker for Bluetooth (Red) about a month ago. I used it once and was thrilled with the sound and form factor.When I came home and tried to charge the speaker, however, it failed to re-charge. It failed to even turn on.I returned the item and purchased another one. The same thing happened!It does not work after use one time.I called the company and left two messages. The company did not return the two calls.The First UnitThe first unit CyFi sent to me only included a USB charger cord--not an AC charger. The AC charger was listed in the manual, howveer, as being included in the package.While the AC charger did not arrive with the unit, a USB cord was indeed included. I plugged the USB charger cord into my computer to try to recharge the unit. I also tried plugging the USB cord into a USB-AC adapter to charge the unit. Neither USB conenction worked.I emailed the company from its website and asked them to send the AC charger. The company never responded. It's been three weeks.The Second UnitAfter the company did not respond to my email request via its website for several days, I decided to simply return the unit and order a new one.The second unit arrived and I used it one time. This time, the AC adapter was included in the package. (No USB adapter was in this package, however.) After one use, however, the unit failed to re-charge. Like the first unit, it became inoperable after one use.I'm really frustrated because the product has so much potential. It's size and shape are perfect for use on my road bike, and it sounded unbelieveable fo listening to music on the road.However, with two units arriving defective and the company failing to respond to phone calls and emails, I feel compelled to warn potential buyers.UpdateI should have updated a few months ago. bought a third unit and here's what happened.Depite my bad experience with the company not responding to my queries (a situation that never changed), I ordered another unit.It was delivered and I used it for about three weeks and it really was great. Really a great sounding speaker and Bluetooth is flawless.Then, the darn thing fell off my bike! I was riding on a really bumpy road and going fast and it went flying off my handlebars and across the road. A car knocked it down a sewer! (You can't make up this stuff.)It was probably my fault. In retrospect, I remember it did not "click" into the mount, and I should have re-seated it.So I ordered yet another unit. By then, the company raised the price (by nearly 50%!, but I was enjoying riding and havign my music so much that it was worth it.This last unit works well and has lasted for about 35 rides so far. It's great.But the company does have quality control and customer service issues.
