I have never yet had to deal with bad customer service from hard to find I have used them a fair bit and at worst I have had a few tatty sleeves and a bit of slow delivery but I have to say if chemical has what you are looking for use them I sware by them they are the first site I came accross and I have spent at least £500 on there site I have ordered things in the bare moments before 5pm and they have still come the next day so I have to say they are truely the best!
