Still Going Strong 3 Months Later.
This set of Razors has lasted me MONTHS. If you're careful with not over-banging them on your sink to remove hair, they will last you that long. I'm still on my initial purchase's cartridges about 3 months later now and getting a close shave.  Maintain your hold by the handle though b/c if you choke up on the grip and hold near the head, you may accidentally press the button to pop off the head. It goes on/off easily enough but is worth noting. It also makes cartridge replacement easy by pushing the button, sticking the head into the cartridge, releasing and done. These have been the best value buy I've ever had with disposable razors and am overjoyed that I found this.
