I've attached a couple of photos and a video to show how the massager works and it's relatively quiet operation.
MY COMMENTS ON THE UNIT:
INTERCHANGEABLE BATTERY PACK (you can purchase a spare and always have one available to swap out for longer periods of operation). Many other brands have a "built in" battery so when it dies you have no choice but to wait for it to recharge. This is more practical for multiple users in the family.
SOLID BUILD & FEEL:
I held some other brands in a store which felt like a cheap toy and "plastic-like". This weighs less than 3 lbs but feels very solid in the hand and absorbs the shaking so your hand doesn't get jittery.
EASY TO USE CONTROLS:
Looked at a few models with lots of touch screen controls where users said they wore out or did not respond. This unit has physical buttons and very easy to use. The 3-way toggle for power is fast to switch and can be done without looking at the unit.
ATTACHMENTS:
There are 4 attachment heads. While some other models have 6, I found these 4 are all I need to use on various parts of the body. The round bulb is the most useful, but I like the smaller node for deep tissue massage.
PRICE:
In the midrange for what I have researched. I definitely didn't want to spend more than $200 where some units cost as much as $500 or more! This is a good price point for many people.
CARRYING CASE:
Some models didn't include a case but this one is perfect and has a soft feel to it. Zipper works great and the compartments fit every piece perfectly.
BATTERY LIFE:
Good. The manual states that the battery life lasts 3 hours, but I found it is more like 2 hours of continual use. Some other units claim longer battery life but this seems to last long enough for any full massage. Again, you can purchase extra batteries if needed and simply pop them in and out. It takes about 3 hours to fully recharge a battery.
