Question: Does the pen work with Huion 420?
Document: I charged it up, and have been using it everyday, 6+ hours a day for a month now and it hasn't died yet. It is also very comfortable and realistic. My only complaint is that it is hard to get it to work EXACTLY at a slanted angle because you have to apply a bit a pressure with tablet pens, but that is to be expected as it isn't a real pen. It is compatible with my Huion H610.
So you are probably wondering why am I sad?I hadn't actually taken the time to look through the questions so this is actually my fault. The pen simply does not work with this particular tablet monitor. Which is a little confusing given that huion uses UC Logic Digitizers just like the yiynova.Side note... it looks like it works for a little bit with the monitor. Without a full charge, it has some response, but it fades in a few seconds.
I bought aH58L Tablet& liked it so much I bought a 2nd one for home. Thing is, the battery pens included with that tablet were inconsistent. The one at work took lots of pressure on the lower button to press and the one at home took lots of pressure on the upper button to press. :PI bought this pen and theMonoprice pento try out.
I didn't like the pen that came with my Huion tablet. It's pretty tall and my hands are small and I don't like using my hand muscles to draw and the added weight of the battery was a strain on my thumb because it was top heavy. This pen is super light, it weighs as much as the pen as if it was empty. Great amounts of pressure.
I am only giving this four stars because the pen stopped working correctly after a day and I returned it. I will be ordering a replacement and if it works correctly, I will update to a five. Sometimes electronics are just defective. In this case, the pen tip pressure sensitivity was not working correctly. However, the seller, Huion, was very prompt replying to my feedback and resolved the issue by asking me to return the pen to Amazon. I did.
Apparently, it's common to get a pen that won't turn off that comes with your Huion tablet out of the box. Fortunately, I recommend getting this instead of a regular replacement pen, and here's why:+Plugs into any USB outlet+LED indicator shows that it's charging+Automatic sleep-mode after 30 minutes of inactivity (within tablet proximity). To turn on from sleep mode, just click with the tip. (This is the only known way to turn it on or off.
So... I bought this pen for use with the Yiynova MSP19U. If anyone has ever used their pens, they feel incredibly cheap, uncomfortable to hold, flimsy buttons, ect. Heck, the portion that screws the battery in is cracked from my grip. So I decided to look for a replacement. I then came to the Huion pen.This pen has a very nice build quality, light (though I prefer heft), and the buttons are actually pretty solid.
I might give it another try after waiting awhile, perhaps a new batch will come in that will work properly.
This may just be from a very low charge... so I will try again later.--------EDIT----------Looks like it does sort of work... I am going to let the battery charge for a little longer. It's cutting out here and there. But it works and tracks with preassure sensitivity. If it does work, this review will change dramatically.
WAY better than the battery-operated pen my tablet is shipped with.
Answer: Also works for the H420 variant.
