Ekrin B37v2 Review: Percussion

Five speeds and medium-length strokes give steady percussion rather than the deepest hits.

Owners say it works well even at the first speed and that a middle speed is often enough.

Bottom line: steady, not the deepest.

Noise and Weight

At 2.2 lb it is a full-size gun in the hand.

Testers liked the angled handle for reaching the back but found it awkward in some positions and louder than some quieter guns.

Bottom line: comfortable grip, average noise.

Battery and Case

Owners praise the battery as the best they have owned and say the gun stays fairly cool after ten minutes.

A carry case keeps the 4 heads together.

Bottom line: days between charges.

Warranty

Ekrin covers the gun with a lifetime warranty.

One buyer received a unit that did not work and had to pay the return shipping.

Bottom line: cover for life.
