Any amp can have problems.
It doesn't matter if it's a hand built boutique amp or high dollar mass produced, or low cost over seas mass production.
Certain brands have proven their reliability over the years, so those are less prone to problems.
Newer companies tend to have higher issue rates.
Point is NO amp maker can claim zero issues with their products.
Bugera is a high volume, low cost amp maker. And they sell a lot of amps.
Given the number of amps they sell, there are going to be more people reporting problems with them, it's the nature of percentages and numbers.
Plus, as everyone should now by now, the internet is FULL of people who will post when something goes wrong opposed to people who post just to say how they dont' have any issues with a product.
This is true on any forum for anything where we spend out money.
The V22 and V55 have had great reliability. The "Infinium" amps are next gen and they too are showing well.
Bugera gets quickly dismissed by those who won't even give it a chance just because it's low cost and over seas made.
The majority of people who are negative to Bugera products have probably never played one.
The over all tone of a certain amp may not be to someone's liking, but that even goes for a Bogner vs a Mesa, or Marshall vs a Fender.
Bugera's tube amps sound good and have very usable tones and features.
Whether or not that tone is great depends on what the player wants.
Bugera makes a wide variety of amps like old school voiced amps, amps with lots of tone shaping, high gain, multi channel, etc...
If you can get a nice sounding amp with good usable features for a fraction of some amps prices, then even if there may be higher potential for a failure, so what?
You pay a few hundred bucks and if something goes wrong you use the warranty and go on your merry way.
If it's past warranty you get it fixed and still go on your merry way with more money to spend on other things.
OP:
Check out new prices for Bugera's. They are very economically priced, so a used Bugera has to be really lowed priced to make it worth it.
