Zeerkeer 3-in-1 Acupuncture Pen Electronic Acupuncture Massage Pen with 3 Massage Heads and 2 Massaging Gel USB Rechargeable Meridian Energy Pen for Pain Relief

I have not had to go above 1. This little wand has amazingly strong intensity. I have used it on several areas and it works. As pictured. Comes with a book to locate different areas of interest.

It's an OK product.. for general use. When product is used above medium power, everything begins to change... it discharges more in to your arm and had you holding.If uses below medium power all is good.

This is so handy to do treaments on myself and family. Good value for the price.

I was hoping to use this as an alternative to my tens machine, as its a pain to set up each time. Unfortunately this isn't very therapeutic. More like a mini shock collar for a dog than a therapy device. VERY cheaply made

Won't charge. Only got to use once.

It works but you will have to be careful on the stimulus settings.

I used this product three times now but have now to recharge it after using for less than 5 minutes. Also as it is cheaply made in China, the handle is not fully isolated and I could feel some of the impulse when in use. I wish this item was made in a model robust material so it would work properly. I do not recommend to buy.

Unreturnable and shocks you as you hold it in your hand. Deserves 0 stars really.
