Great pen and great price!
Color: White
I’ve been using this pen ever since I purchased my new iPad. Let me tell you that it works great. I use my iPad mainly for writing notes at work and I use it every single day. The pen has help up well. It comes with 4 replacement tips, but so far I haven’t had to replace the tip even though I use it extensively to write. Battery life is pretty good and it charges fast. To me, there is absolutely no reason to spend money on ahig end pen when this one doe essentially the same thing!

Great dub
Color: White
Love the pencil and price. I use it to design tattoos on procreate. It works great. No issues connecting. Like an apple pencil without the price. Good dub. One downside, the paint is chipping off the pencil. Not a big deal.

Works very well with the iPad for the price
Color: Blue
The pencil works well. I like that I could choose a color. It has pretty much the same dimensions as an Apple Pencil Pro but not quite as much heft. It still feels fine and works just fine. Writing is smooth and it works in Procreate; however, I miss the pressure sensitivity being able to tap for some functions that you’d get with the Pencil Pro. I appreciate the charge indicator and it is easy to charge although the protective cover over the USB-C charging port is a bit of a hassle since it is small and could easily be lost. I like the power button on the top of the pencil as it feels natural to click it on and off sort of like a ballpoint pen. I also appreciate that it will stick to the side of the iPad magnetically like an Apple Pencil even it doesn’t charge that way. For the most part it just connects and works; however, I have had a couple instances (maybe after charging now that I think of it) where it will take a few tries sometimes switching Bluetooth on and off before it connects again, but then it continues to work between power cycles of the pencil and sleep cycles of the iPad. Works much better than a standard stylus, but is not compatible with an iPhone.
