I used them twice, in 2018 and in 2020 and apparently they sell faulty items. Both my items were faulty and I read few more such comments from other buyers. They succesfully replaced my first item, there were no problems despite the long waiting time (item from Czech Republic to UK). They were supposed to replace my second item, the collection taken place on 8th January, I was updated by both the text messages and emails and they informed me that in the next two days they would send me a replacement. After three days the courier from Royal Mail (they use DPD) delivered my item. I was shocked because it was very quickly but it appeared that they sent me my old faulty item back, it never left UK according to the tracking history and on their website they told item replaced. I was so furious. Because of the Brexit they asked me to send the item to them and pay for the delivery but said they would refund me for the shipping cost (have it in writing). So I sent it to them and it was in transit for more than a month. Finally, I was refunded for my item but they didn't pay me back the shipping cost so they were lying about it. This experience was a nightmare. However the contact with them was very good (emails and text messages).
