I have had it for a while now.. you can read a review here:

It's been able to charge everything I throw at it... the only downside is that you need 12v power supply.
Otherwise it's been great. It's got a decent memory on it, though I'd love to have more.. I think it's up to 8? It does have motor break in, but I haven't used it yet.

Just my 2 cents.
