A great product, does exactly what it says on the can. However, is it just me or does anybody else have a problem keeping the power usb plug in? If you knock mine even a fraction, out it pops and stops charging. Apart from that minor design defect, a 5-star product!
Update: having posted this, I remembered that the device came with a USB lead. On checking this, I noticed that the plug was significantly longer than my standard, Samsung, one. When I inserted this lead, it made a considerably firmer and more secure contact. Rating amended accordingly, now I need to remember to only use this lead to charge up the device.
Great customer service from the manufacturer, too!
