Another LastPass user of ~5 years. I was actually dreading the switch, just because of the amount of time I had spent using it (mostly always Premium). That and I have a workflow within the family for sharing, etc.

I planned on a week long switch over to make sure things went smooth. However after switching, and validating all common accounts has been imported correctly I just never had to open LastPass again. This took all of 2 hours.

BitWarden has the upper hand in three key areas for me: Android, FireFox and CLI. The LastPass extension for FireFox has become downright useless and that was the main catalyst for me switching.

I've switched now about a month ago and can't imagine going back. It just works like you'd expect in most situations. I'm fighting it less than LastPass and my store of passwords is all cleaned up and far more sanitary. LastPass lets you make a mess far easier, so a nice side effect of BitWarden is that the structure is more prescriptive but I've been yet to bump into an area where it's blocked me from doing what I need.

Highly recommend BitWarden if you're fed up with LastPass and FireFox.
