You're right about there being a lot of chargers out there but all are not
created equal. I've seen a lot of different chargers in use over the years
while flying in the pattern wars. Some work OK, some don't but the Sirius
is the best and easiest to use I've ever seen. It's not just a peak detection
charger , it's much more. It conditions and rejuvenates depleted packs.
One of my long time friends owns and operates his own hobby shop and he
doesn't even sell Sirius but he uses one. They have a small computer built
inside to control functions and they're idiot proof. They're almost impossible
to hook up wrong and even if you do it won't hurt anything.
Oh, and they do have Li-Po chargers too.
I attended the Florida Jets Rally and saw how many fliers trusted their high
dollar jets to Sirius so I think I'll stick with it.
I guess everybody likes what he has or he would not have purchased it, but
I don't think anybody would be disappointed with Sirius equipment.
