My oldest Belka DSP was handed over to a friend who didn't report any button failures so far, the encoder had become a little erratic after a while tho (doesn't give impulses over a few degrees of its turning radius or something). The encoder of my -DX got a bit of that disease too but no button issues either. My two v3 Belkas (yes, I have paid for all of them and no, I don't want to cook a soup with them ) have no button or encoder issues.
The first new v3 Belka I got had developed an issue that turned out to be a bad solder joint and I had to send it in for repairs. Since it apparently enjoys traveling so much it became the one I dragged around everywhere for almost 2 years now and I dropped it numerous times from ~3ft height onto various undergrounds, grass, metal (car door sill panel), asphalt/concrete because it hopped out of my breast pocket when I got out of the car or the suction cup I use to fix it to the side window fell off with the radio. It took that all without obvious blemishes.
Not surprising given the 1.5mm aluminum top+bottom shells / 1mm side panels, at that small size this means it could be one of the most mechanical robust receivers ever. It also has (tested) excellent shielding properties, nothing gets in w/o an antenna connected. However, nothing is made to outlast you anymore.
Should a button fail or an encoder need replacement - the construction is tiny but also very simple and accessible, and it's made of components commonly available on the consumer market. The buttons are regular "tactile switch" standard SMD parts and you can replace that with the best one you can find, just like the encoder.
