I bought the 400 watt upgrade from them. A-1 service, great product! Also, when I was sent another customer's part by mistake, having already returned one other before, Mr. Rayski said for me to just keep it for being so nice as to return the errant first one! Starter solenoid I think it was. Of course that doesn't happen very often but his manner is so refreshing! BTW the other customer got sent the part they wanted!
Both John Rayski and Rick Jones from the other supplier Motorrad electrik?, are just super people!
