I love gadgets, electronics and computers. I know what I'm doing testing the items I sell on Ebay and have equipment to test almost everything. Until know none of the buyers complained about damaged, defective or nonworking item (apart from one liar)
Bubble wrap is my favourite material. All The items I send are properly packed. Sometimes I even make my own cardboard boxes to better accommodate the items I post. I do it with some pride. One of the things I always keep in mind is that items can be damaged during post and when that happens is a hassle for me and for buyers so I'm very careful and evaluative in the way I pack items. To finalize I always wrap packets with packing paper.
