I purchased this item to replace the equivalent Remington Shaver Saver product I'd been using. This item, in 4-oz size, is less expensive than the Remington item, and Remington doesn't make/sell a 7-oz size item. This item works as well, or better, than the Remington item. I carry 1 in my suitcase at all times as I travel frequently for business and I've never had a problem with it. It works well and I use it after each use of my rotary electric shaver. I'll continue to use this item as long as I'm still shaving!
