This is the Panasonic electric shaver, the Lamdash ES-ST29. It's wet/dry compatible, so you can use it in the shower. I used it for business trips, but I'm selling it now because I've bought a new shaver. The frequency of use was low for its age. I cleaned it and applied special oil to the blades before listing it. I think the shaving performance will improve if you replace the blades. In my personal opinion, it works almost as well as a 5-blade shaver. There may be some dirt that I couldn't remove, but I've confirmed that it works, and there are no noticeable scratches or stains.
