An efficient service which actually values customer careI was impressed with the fact that delivery was sent as a text to make the delivery slot A precise time. So often, companies are unable to do this and you managed to fulfill what most customers need. Frequent dialogue from the company.

Beyond bad!!!!!!It has to be some kind of joke that you would ask for a review of the transaction that I just opened a papal dispute for. I never received the goods. You refused a refund or to resend and told me to check with my neighbors. You want to know what I think.

04 September 2012 Good service let down by over the top P&P 隆锚3.99 for P&P on 2 small and lightweight handles I feel was over the top. For this type of cost I would of expected next day delivery from other major online provider. With that said the rest of the service was spot on and the website was a breeze to us. I would use again and suggest to family and friends but would definitely shop around first to see if you can limit the damage on the P&P.
