I like them, especially for retrofit solutions, but they are not perfect.
My biggest complaint is lack of filter surface and options to catch dust and other things. This can be "fixed" with an auxiliary filter unit if it is a concern -- you know, one of those units you stick on a table or in a corner.
I have some experience maintaining minisplits and discovered some irritating issues. In certain conditions, they could get moist inside and catch dirt on the condensing moisture. This would eventually cause a disgusting black layer build up on some smooth internal surfaces. After a period of low use (spring/fall), the next time the fan kicked high, chunks of crap would fly out.
It is difficult to take apart and clean these areas. What I've read is that you can fix this issue by forcing the fan to run a bit higher or longer, which stops the internal condensation issue. Oh, and this is really only a problem in very humid areas like Southeast USA.
I think installers are learning how to deal with them. Like so many smart devices, there are a slew of configurations that must be done for a good install. Most of these are hidden to the end user. The defaults are not always appropriate for every application. Good installers know what to do.
Hmm, could the black stuff be mold spores?
It could be spewing out spores before you can tell because they could be microscopic but you could still inhale them.
