I bought a ego Mega 900mAh 2 complete units. I thought health cabin had the best deal because of USA vendor's were splitting the units up but adding adapters,etc 1 atty 1 cone 2
batteries but adding a 510 to 901 adapter.......doesn't allow you to have *2 complete pv's .....so I bought it on Sept 20 2010 within the first 2 weeks a battery and an atty died and I did the warranty exchange mailing it back to them Oct 8 I'm still waiting for it which they first said, it was mailed out Nov 12 then Nov 22 ? They keep telling to be patient? Im still waiting for my first battery and the second just died 2 weeks ago. My point is buy from an American vendor if you live in the u.s .......the latest is "what's your account #, I had a memory lapse". Along with its bad weather since Nov 1 and they gave me a China air tracking # that is t recognized ........by the time you get your replacement if a 3rd goes bad 6 months have lapsed! Look for an American vendor with at least a 6 month warranty.
My brother went with a riva which he upgraded immediately to a 900mAh battery
Oddly enough or maybe not your first order from healthcabin arrives promptly........and I know that ems is faster but China airmail ........3 months ?......... I could've had it driven here quicker. Buyer beware.
