As a concerned parent of teenage boys, I was looking for the perfect product to keep them safe while they groomed. The search ended when I found Groin Hair Trimmer - Ball Trimmer- Pubic Hair Trimmer, Men Shaver, Waterproof Male Hygiene Razor with USB Recharge Standing Dock Link. It's so easy to use, and it provides such a smooth shave that my sons don't even need my help now! In addition to being intuitive and user-friendly, this trimmer is also super powerful and has a long lasting battery life—up to 90 minutes after fully charging in its rapid charging USB dock station! But most importantly for me as an anxious parent is knowing that this product keeps my kids safe because it features advanced protection technology designed minimize nicks or snags; plus an ultra sensitive blade with high powered motor ensure effective trimming without pokey risk. Plus the device boasts water proof protection making showers rendering efficient haircuts possible too! My son's friends are always asking where they can find one of these trimmers now because they think it's pretty cool - though *I* like it most because it gives me peace of mind knowing how much safer and easier their grooming experience has become. Highly recommend this awesome trimmer!
