Good

Very good experience. Fast shipping.

Helped sore muscles without side-effects.

Great battery, I liked it so much I had to order another. Service and shipping were very fast. Will definitely order again.

Speedy delivery. Excellent battery, one of the best I own.

Works perfectly, better deal than amazon

Nice battery. Seems to last long time. Good indicator for temps. A little large in size, but works well.

It gets pretty hot and has a tendency to burn cartridges after longer hits even at low voltage.
