A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
I installed these last weekend. I trimmed them down exactly as the guys at Web Bike World did, no damage to the heating elements. I look forward to cooler weather so I can try them out. I have used "Hot Grips" on my last 3 bikes.
