Sharper ImagePowerboost Hot + Cold Dual-Temperature Massage Gun Attachment - Instant Heat & Cold, 6 Temperature Levels, Compatible with Powerboost Massage Guns, Black

I am so surprised with how cold this thing gets! I was fully expecting the heat to be great but the cold to be more of a novelty. I'll be the first to admit: I was wrong. The cold gets REALLY cold! This has significantly helped me with sciatica pain and has helped my husband with back and shoulder pain. We wish the batter ly life was a bit longer, but overall, we're impressed.

This product either heated up or cooled down quickly. I was skeptical when I ordered it, but it worked surprisingly well. It stayed heated or cooled for about 20 minutes which was long enough to massage an area. It fit into the massage gun and operated well.

This is amazing. It has an interesting design but it heats up and cools down fast. It’s super cheap for such an amazing addition it also comes equipped with 3Pieces to fit your sharper image machine.

Does not fit the brand or gun it has listed has working.

Heats up and cools down fast. Holds a decent charge too.

Having the addition of heat and cold to add to the massage gun is the best

Did not work with the massager it was listed with. Will retry later

One of the best decisions I’ve made was to purchase this attachment for this massager. Love it. Highly recommend. It’s only been a few months, but so far, I have no complaints.
