This is a very popular item - I purchased two of these units a week apart and I had to order them in. It is convenient and a useful product with the four power point sockets and four USB ports rated at 2.4amps per USB with a maximum current capacity of 4.2amps. Unfortunately the USB ports failed after a week of use on one the second one I purchased. The power points were still o.k. PB Tech were good to offer to replace it but there were none in stock and I took a credit to my account.
