I’ve had one of these for a many years, and I really like it, although finding a replacement for the single ML2032 battery was quite a headache the first time it died.
It turns out that a popular mod for these was to disconnect the panels and replace the ML2032 for a regular old non-rechargeable CR2032. The keyboard uses so little power that it lasts several months with a single battery.
It does make you wonder what was the point of the solar panels in the first place. If you replaced them with single use batteries they’d actually last longer than the entire lifespan of the rechargeable battery 😂
The Wikipedia entry has a pronunciation guide:
English: [bɑːrsəˈloʊnə]
Catalan: [bəɾsəˈlonə]
The first a is a schwa and the o isn’t rounded. Honestly, it looks quite similar to English, to the point where there might be some English dialect that sounds exactly like that.
