So far so good.

Great price on product sold out at my "regular" place. My only negative was that I didn't get info to track the package or know when it would be delivered -- until AFTER it had been delivered. But that's not such a bad thing; it was a nice surprise when it showed up! I'll be recommending you to friends.

Great Customer Service, shipping and billing address was different. They called me right away to verify this was no fraud. I will order from them again in the future.

just want to make sure I got the right ones.

Easy shopping, but would be nice if the picture matched the model, it would have saved me 20 minutes of waiting on the phone for customer service.

Found correct item easily and checkout was fast. Once I received the item, it fit perfectly and works as expected.

easy navigation good prices now well see about shipping
