Having tried a few similar products, this is by far my favourite. Battery life is around 1.5-2 hours using most settings, or longer on the lowest. Feels incredible and having a remote to give to your partner makes for some interesting times. One downside is the remote signal does get somewhat easily blocked, a plus is if you misplace the remote the power button on the device will cycle through all settings. I fully recommend this product to anyone looking for this type of device.
