I have (and love) a Sharpsicle — pleasant tone, but not a big voice. It would be fine for a quiet nursing-home room or a small lobby or day room, but it wouldn’t carry far in a big room with a lot of hustle-bustle or loud beeping machines — but then again, what would?
The two or three lowest strings are kind of plunky as someone else said, but the rest are fine. It holds its tune very well, once it’s settled in. For the portability and price, I’d certainly recommend it.
Good luck! Let us know how it goes.
