SkingwaHot Stone Massage Warmer - Electric Heater With Heating Bag for Massage Stones (Heater Bag Only, Stones Not Included)

Definitely will use

When only load half bag to three quarter (no stone overlap), the efficiency is the best. Heating very smoothly, no over heating. It works for me well. Actually, the heating will not reach too high temperature. If you are looking for something can burn you, not this one at all.

持ち歩くのにどうかなと購入しましたが、温度も長くもちます。石が熱く感じないように布に石を包んで使用してます。私は熱いかな?と思いますがお客様には好評です。イベントなどで利用中。

Adding my 2 cents here. This bag works just fine but you need to have it plugged in at least 90 minutes. The only thing I wish it had is a auto shutoff option. It isn't big so the more stones the longer it will take to heat up

I like that you just plug it in and it does the rest. I use to to relax. The stones do not get too hot in the bag. You can use the bag to carry everything you need even while traveling.
