Halfway through Black Friday last year, my sister and I wandered into a store that had three Homedics massagers set up in chairs for customers to try. Half an hour later, we reluctantly yielded the chairs to others, and my sister knew the only thing she wanted for Christmas.
There is a basic shiatsu massager (model SBM-200H) priced at $99.99, a mid-level quad roller (QRM-400H) at $159.99 and a third model with added shoulder massage (SBM-500H) at $199.99. All three use oscillating ball or roller massage that travels up and down on tracks, and all three provide optional heat.
