Review on HEALTHLAB Deep Tissue Massage Gun: Powerful Percussion Massager for Athletes - Lightweight, Quiet, Portable, Long Battery Life - Relieve Muscle Soreness and Aid Recovery - 20 Speeds, 6 Heads - Men & Women by William Dean

It will not be fully charged even if plugged in overnight. According to the product brochure, it should charge up to "99"; The max I could get was 90. Worse, the battery drains too quickly. Last night when it showed a 60% charge, it dropped to 20% in less than five minutes. This is the point where reloading is recommended. Otherwise it's good, but I'm sending it back because the battery performance isn't acceptable.
