Ordered a Samsung Galaxy A11 11" tablet on sale and as always, it is fantastic! Fast delivery, well packaged and 100% genuine (checked via serial number). Bought a few items from here now will continue to do so at these prices!
1st time purchase from A1 so was a little apprehensive having fallen foul of a spoof website recently. No need to worry though, purchased a Samsung S25fe for the best price in could find on the web at that time. Good communication via emails and delivery within a couple of days. All good.
The price of the phone wae very competative, the ordering experience was simple and effective, and tge delivery was faultless.(very quick and secure). Thanks.
Found this company whilst searching on google for a new smart phone. The price was far cheaper than any of the other companies.
Delivery was extremely prompt, ordered the phone on Monday and it was delivered on Tuesday.
Would definitely use this company again.
