Very reasonable shipping time, packed very well for the product..!! Thanks..!

in stock and best price!

Just wished I could get my parts sooner rather than 2 months later

A piece I ordered arrived broken (in transit from rough handling by UPS). I called customer service and a replacement part was at my door THE VERY NEXT DAY !!! I didn't think that rapid of a response was even possible. You have the BEST customer service I have ever dealt with. Your price and shipping on what I purchased was also good. 5 or more stars on my entire experience. Sincerely, Chuck Johnson
