The encoders are rootless, look different from the seller’s pictures, the only marking is extruded on the plastic part of the T case in a rhombus. The metal part is all kind of scratched.
Buttons, as claimed by the seller, manufactured by Omron(whether this is true - without a clue, the only thing I can say, those who arrived are quite similar to the picture on the product page). We got without a track in 3 weeks directly to the mailbox.
Of the external flaws - the conclusions on the pair of buttons are partially oxidized.
But it is easy to get along with rosin.
A bit of practice - in the “rapoo” mouse bought at a cheap price, the encoder died (began to twitch in the wrong direction) after a week (!) Of use.
Old and new:
In another Trust purchased offline, through~ six months and an additional button began to double. Then the encoder was temporarily moved and lubricated with SI-180, which helped him. The button has been replaced by a freshly produced one - the sensations from the old and new are noticeably different, the new one presses harder and clicks more deafly. Subjectively, I like the old one more.
Button after replacement:
In general, the replacement was successful. How much they will live - time will tell. If there is anything, I will unsubscribe later.
plastic body was surprisinglyIt’s quite elastic, and it was possible to remove the cover without damage (remembering some usb-connectors, in which the latches crack not only with the reverse opening, but with the first snap).
