Lenovo Precision Pen 2 is an active stylus released together with the Lenovo P11 Pro tablet.
At the time of this video, there isn't much details on the exact retail price and where you get buy replacement pen tips. I bought this pen for US $50 as part of a bundle with the tablet. It's likely the pen will be priced higher when sold separately.
The pen supports WGP (not sure what this is) and AES 2.0 (Wacom Electro-Static technology).
Body of the pen is made of metal and build quality is solid. The functionality of the two side buttons will vary depending on the apps you use, and most apps do not allow you to customise the shortcut buttons.
At the back of the pen is the USB-C charging port. Battery life is rated to last for 100 hours which is good for a few days of continuous use. I do prefer removable AAAA batteries though. Diameter of the pen is just slightly thicker than a typical wooden pencil.
The pen has a good length, thickness and weight which makes it comfortable to hold. It's slightly shorter than the Apple Pencil.
Only replacement pen tip is included. It's difficult to find replacement tips right now. This is a real concern for artist who draw frequently and may wear out the tip fast.
The pen tip is tapered in design and the tip of the tip has a matte surface finishing that provides slight friction on glass. The pen tip glides smoothly on glass and thankfully isn't too slippery. I don't recommend using the pen on a matte screen protector as that will wear off the tip even faster.
That's the silicone case included in the box.
On the back of the silicone case is double-sided tape.
If you want, you can stick the silicone case to the hard plastic backing.
Looks like you can run a key chain through that hole.
Clip Studio Paint is the only app I know of that allows you to adjust the pressure sensitivity curve.
There is slight wobble with slow diagonal lines. The S Pen can produce slightly straighter lines by comparison.
Lines can taper but how well they can taper will depend on the app and settings you use.
Line transition from thin to thick is smooth. Initial activation force is minimal is quite sensitive at low pressure.
So the only issue when drawing is actually the diagonal line jitter/wobble.
Tilt sensitivity works great with Autodesk Sketchbook. Lines can transition from thin to thick smoothly. When used with Concepts, the thin-thick transition is more abrupt. So how well tilt sensitivity is supported depends on the app you use.
It's easy to maintain consistent pressure to draw line with uniform thickness.
Drawing performance with Clip Studio Paint is pretty good. When drawing with my normal speed, I don't see the wobble affect my art. Maybe it's also because Clip Studio Paint has settings to smoothen lines. With Autodesk Sketchbook, I notice the line jitter/wobble more easily.
Pressure works with Medibang Paint Pro too.
Writing performance is pretty good. Most apps are able to capture my handwriting reasonably well, with Wacom Bamboo Paper app being the most accurate. It's a good pen for taking notes.
