Někdo na netu tyto kondíky hodnotil:

"I've bought bags of Chengx/Chengxing capacitors and never had an issue with them in the 5 or so years I've used them. Though, they may not be the same ones you've used, since mystery meat Ebay caps can be branded anything. I bought my stock all from one seller that I found to be reliable, but unfortunately they stopped selling them late last year and I couldn't find another supplier. They aren't the best, but they also aren't the worst. I've used them in quite a few applications though and haven't had issues with them failing yet."

"No matter what, I probably wouldn't use them in anything critical, anything which undergoes any kind of stress, or anything which is difficult to service. They definitely do fail (although not so often as the ChongX fake/clone caps). They're like the low end of the cut rate, although definitely better than absolute garbage caps. I think your time is usually more valuable than the few cents you'll save, but even if you want a more economical option there are much better choices available."

Zdá se že Chengx má odlišné rozměry:

13x25 Ir=193
