    Well they were very responsive for my questions. After receiving the product i had a question and they responded within a couple hours yes not days which is almost unheard of these days. Shipped as they said it would very fast i was impressed alot of sales these days say it will arrive by a certain day and it doesn't. The packaging was also first class, i was also impressed on that, box wasn't damaged either. They were spot on!

    Absolutely amazing and perfect transaction!  The seller made an exceptional offer on this rather expensive item, and I was thrilled to accept it.  shipping time was amazing as well and being new and using Federal Express. It arrived in perfect shape and exactly as expected. I highly recommend the seller and will be planning to purchase from them again in the near future. They also had follow up communication to be sure that everything was OK and I appreciate that as well. Thanks !

    Sent them an email asking about shipping and to be sure the springs were indeed in stock. They emailed me back right away and confirmed they had them ready to ship. So I ordered them on a Wednesday night and had them by Friday afternoon! Awesome customer service!
