Manscaped is also good. I can just do just as good of a job with a regular razor for cheaper. 

Speaking of which, both Dollar Shave Club and Harry’s make good products. Neither is better than the other from my experience. Just see which one has the best coupons available.

Dollar Shave Club lost my business when they made their online razor blades incompatible with in-store razor blades. Clearly a money grab move, believe it happened after they got bought out over a year ago.
