Bought a battery from these guys back at the beginning of March. Nearly 8 weeks later and it has not arrived. I've tried several times to email customer support (the only contact method they provide) but have had absolutely no response. And, yep, I've routinely checked my junk mail so there's definitely been no reply (and certainly no sign of the goods).
In the beauty of hindsight, I was rather foolish. A quick check would've showed that the website is actually registered to China, not the UK, so there is no UK contact, and the several spelling mistakes throughout the website should've been a giveaway...
Avoid anything which sends paypal payments to shuaijie liu (this is where the payment goes from the website).
Hope this stops others making the same mistake! Scam website - avoid!
