I used a MS2-300 for years until it finally broke. I bought the MS2-390 in hopes it would provide a similar shave and because it tends to have the least expensive replacement blades. So far I'm pleased. It shaves almost as well as the MS2-300. Yes some spots require multiple passes and some skin stretching, but I find this is common for electric shavers. While it is loud, it is noticeably quieter than the older model and appears to be more water resistant. The build quality seems a bit better as well.Unfortunately, there were a few regressions from the older model. The "pop-up" trimmer moves up very slowly (the 300 popped up instantly) and unlike the 300, the 390 has a large power adapter that can make it difficult to plug in anything else when it is charging.
