I really like the six levels of intensity it offers, as it gives just the right amount of pressure and vibration where I need it. The heads are pretty standard, and a good selection. It is helpful to have the different heads, since they help you better target specific muscles and joints better.
I really like that is is usb charged. I always have a USB port available, so this is truly a universal option for me. I also like that it comes with a wall adapter. You can never have too many of them.
The battery life is excellent, as it lets me go through many sessions between charges.
It is a quality unit, very sturdy, and solid.
On of the things that makes this package stand out from others is that it comes with 4 replacement collars. These collars wear out over time. Having replacements means that I can significantly extend the useful life of the massager. That really adds a lot of value to the unit.
The only thing this set is missing is a carry case, but that is by no means a deal breaker.
The massager runs for hours, and comes with the 4 most essential heads you can have, and comes with 4 spare collars. You simply can not go wrong with it.
