For a close shave, you best use these razor cartridges within the first 2 weeks of opening them. This razor is comfortable to hold and easy to use. The blades are sharp for the first few weeks, and the moisture strip is slimy, but makes shaving really close for a few weeks. After the first few weeks, the moisture strip pretty much dissolves and breaks off, so you have to change the blade pretty often, which can get annoying because they tend to get really expensive, as most Gillette razors do, unfortunately. These blades and the moisture strip, when newer, make for a really close shave and smooth legs. The head is rounded, so you can easily shave quickly around knees and ankles in order to get all those stray hairs without worrying about nicking skin or slicing yourself. I continue to buy these refills because other than my Gillete men's razor that I buy refills for, this also gives me a really close shave, and I hate having stubbly legs. I hate spending so much on the refills that I have looked at other options, but disposable razors suck, and I haven't found a great alternative yet. I'll keep looking until I can find something that works like this but doesn't cost as much.
