Good Morning!
I purchased a pink HJC helmet on Monday evening, and it arrived yesterday. I am writing this email to thank you profusely! The shipping was fast and was packed really well! I had requested it be in a plain box as it was going to a public place, and it certainly was! The full wiring kit (not just the cable) was a pleasant surprise, and the hand written note inside the box on the invoice was a lovely touch. (Not to mention the wonderful price of the helmet and electric shield!!!)
I cannot speak highly enough of your company and have already recommended to friends they shop there for anything they need!

Thank you again for going the extra mile, it really is appreciated.

I was on your website last night and sent an email to your "Contact" address asking if this product was in stock. It was nice to get a reply right away, but even more impressive because it was 11pm! Thanks to Mike for his help. - Bill
