LIANXUE TTC Mouse Wheel Encoder Yellow Core Decoder 48 Million Life Expectancy for ROG Gladius III

First off, I did not use this on the intended product. I purchased it to replace the scroll encoder of the Elecom HUGE HT1DR . You will need to swap the connector in order to use this. Other then the connector it seems to fully functional. If feels stiffer then the original encoder but I think I prefer it this way. There is a tab on the metal face side but it wasn't an obstruction for my installation.

My Razer Naga Pro was having a problem with the scroll wheel where it would randomly scroll up while I'm trying to scroll down and vice versa. I found a Reddit post (shoutout lordchilli) that said one of these TTC sensors would work as a replacement. The TTC sensor he linked was no longer available but this one looked the same so I ordered it. In the Reddit post he said he needed to de-solder and reverse the white wires but I did not have to do that. I decided to try just putting the new sensor in and confirming that it was upside down before busting out the soldering iron and it turns out there's no need with this sensor. The scrolling was already rightside up as soon as I put it in. So TLDR, if your Razer Naga Pro is having trouble with the scroll wheel, this sensor should fix it. I also bought a pack of new mouse feet from Amazon because the ones you have to peel off to get at the screws on the bottom will never feel the same after you peeled them off.

Works! Had to replace the wheel encoder on my ROG Gladius III Standard. It was starting to have issues where the scroll wheel would jump all over and often back scroll. This was after a year and a half of heavy use. Unlike another review I was prepared to solder the old wire to the new encoder but it was not necessary. The over reviewer must have another version of the ROG Gladius III. This encoder is slightly stiffer then the original one in the mouse. If I run into any trouble I'll report on this review with an edit. Correct Size for ROG Gladius III The price seems a little over as I seem some for cheaper. Unsure of the quality as I just installed it today.

It worked great on my Dell mouse!

I've owned my Razer Naga Pro for 3 years and found myself having the same issue where my scroll wheel was no longer precise. I also saw the Reddit post which said a TTC encoder would work and another (shoutout SumonaFlorence) who posted a detailed disassembly guide. This encoder's design is very close to the original (see photo, TTC on left, Kailh on right) You can also see how worn down my original encoder was, explaining why the scrolling was no longer precise. The wires were already in the correct orientation as another Amazon reviewer mentioned, which is why I went with this product. The board connector is almost a perfect fit, just a bit loose, but I'm not worried about it. You will need new mouse feet "skates" after disassembling your mouse, I went with "Corepad". My original skates were due for a replacement anyway. Total time for the disassembly, cleaning, and replacement was about 1 hour. Considering I spent $20 for these encoders and mouse skates, it was well worth it over buying a new mouse. My Razer Naga Pro feels brand new now, and if this encoder wears down like my original did, I have another at the ready.

So I cannot fault these LIANXUE TTC encoders at all, however, they were not a direct fit for the TTC encoder in my Perixx trackball. However, they were close enough that I could make them work (remove harness, cut tab off metal faceplate). After that, it mounted into the encoder board in my trackball and I was back in business. Good tactile feel when scrolling, no ghost scrolling or jumping. 3 thumbs up!

Encoder was too stiff to rotate nicely. I thought it might get more smooth the longer it was in, but it has now snapped the connection to my naga pro scroll wheel and I have to buy a new scroll wheel which will take close to 2-3 weeks to arrive. Definitely avoid and get the green encoder instead2

They work as replacements for my razor mouse wheel encoder. No issues at all and perfect size. What else can I say?
