Product review (1 stars): Beware! Make sure your Avanti purchase (of any size) has an authorized repairman in your area.
Please make sure that your area has an authorized Avanti repair company in your area before you buy.
I bought one that was defective, was informed there was no support in my area and I could get it replaced by cutting off the plug, removing the ID plate and sending both with a 10 dollar processing fee to Avanti.  In 10-14 days they will send a replacement. Of course you have to unload it from the truck, install it yourself and figure out how to get rid of the paper weight range that's left in your charge.
