Wow, what a deal. Great price on the product and shipping. What else can I order from these guys? They'll be my first stop.

Easy shopping and great payment option with Amazon.

Great products, and pricing

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

Great price and easy ordering. Had a problem with the sensor not turning on the fans. Used an old sensor and everything is working good now.
