Works well, have used it & held it for awhile. One of the older altcoins and has been around for several years, not a fly by night. Several of the original guys involved are coders & community members who were early bitcoin adopters. The ring signatures have been reviewed by some big names and seem legit tech wise. It uses a completely different code base (cryptonote) than bitcoin and this is why wallets are not as common for monero like Bitcoin & other coins. No hardware wallets yet, 1 web wallet and a beta gui.
Also cryptonote code base came out of nowhere back then and was questioned but audited too.
