They only stock XTAR but that doesn't mean anything. They probably prefer to stock items from fewer supplies to reduce storage space.I have the d4 and the i8. But... are they better? Absolutely no idea. I think it would be extremely hard to compare.
Which ones do fogstar stock? Stands to reason that the battery experts would know a thing or two about battery chargers
If you want China prices.. Use FastTechI'm planning to pick one up the next time I'm in China so I want to do a bit of research ahead of time.
They are both Chinese brand and I don't want to pay UK prices.
