Review (2/5): Not as great as I expected.
These cartridges don't fit very well. You really have to work them in. Then they don't work very well. Maybe too much fluid. Not sure why they spray the counter and don't drain very well from around the base station. When I remove my razor the next morning, the razor is still wet with solution. I have to dry it off before I can use it. I won't buy these again. Not worth the savings.
