Plastic cheap. But it looks good, it works. It hits the current on both sides, on the side of the sensor and in the case. Professionally, this device is better not to use.
The order went to Belarus for almost two months. I think because it was ordered until the new year, when the Mail is overloaded. The handle works. English instruction is attached. Be sure to use the gel, otherwise it hurts with current. In general, I'm happy, I recommend the seller.
Super fast shipment. Looks better than the picture. Haven’t tried yet.
Everything is fine! Electric pens Super! The current beats in the holding hand, because so should be-the electric circuit should be closed. The seller is sociable, contact and attentive. Initially ordered 2, but one of them did not work and the seller sent a new one that works fine. The goods are satisfied, I recommend ordering from this seller.
