I purchased 3 sets - two twins *Chiropractor 1000" and one full set, a chiropractor 3000. The salesman was very helpful and there were no high pressure sales tactics. I appreciated the fact that he didn't try and push me towards a higher price name brand. I purchased thes sets Friday night and arranged for delivery the next day. The delivery men attived when promised and were both efficient and polite. Overall this was a great experience.
