Not the worse, but definitely room for improvement,
Update: Channel 1 Died in less than 2 months. Leads that won't work in channel 1 work fine in remaining channels.<br />Initial Review:<br />Gradient intensity & 24 modes are comparable to many settings achieved using analog TENS/EMS. Not having to buy batteries & 4 individually controlled leads if desired are definitely an upgrade.<br />Controls are straight forward easy to understand. It would be nice if the buttons were also back lit. Although the button layout are conducive to fumbling in the dark. I found voltage became increasingly unstable once battery fell below 40%. I started getting shocks one channel at a time. Despite the fact pads had not been moved, controls are locked & I was already enjoying simulation. The pads are easy to wash & frankly must be after/before each use. There is a small amount of residue from adhesion left on skin but easily removed. Failure to wash pads before/after each use will result in skin irritation, rash or worse. Blot pads dry to remove excess water. Clean area of clean skin with alcohol, peroxide etc not just soap & water before placing electrode.
