I have the JAMJAKE K10 stylus (JAMJAKE K10 stylus) w/ palm rejection & I can't tell any difference from the apple pen. It has a 1.5mm tip & a 90min charging time which gives 20h of continuous use. There's apparently a newer model, the K11, that has tilt detection (whatever tf that is), a 1.2mm tip, & charges in 60min, but only has a 10h continuous use battery life, so yeah. Some reviews complain that there's no pressure gauge, aka your writing looks the same no matter how much pressure you apply, but I have zero use for a feature as such because I just use it to take notes on notability/goodnotes. Other than that, the reviews are fantastic. I've had mine for a little over a year now & have no complaints thus far. If you were to need more tips, the first question is someone asking about that, & the response posted has a link to the tips for the pen. Sorry this was such a long reply, but I 10/10 would recommend this pen.
