I do not have a Note 10 but I have a Note 9 with a fairly slim case and it just fits in the charging cradle of the Taptes gen1 wireless charger. There is a .4mm difference between the 9 and 10+ and I would say that with my case it is about the same. So a Note 10+ with a thick case may not fit.
No, it works perfectly for what it does. BEST thing about this is that, in addition to the 3 coils of wireless charger (for 2 portrait charging or 1 landscape charging), there is a hidden USB C cable already hidden on the ledge of the charger. They don't advertise this feature but someone told me about it.
Wire or wireless charging is not hard to do. Everything you can buy from anybody probably came from the same source in China.
