Ok, so I did a search and read some posts. First of all, in many of the threads, there were many folks who chimed in and said they had zero problems.
Second, of those who had problems, one thing we do not know, is were they trying to run slide rooms in and out while the trailer is not level ? Having spent many, many nights in various campgrounds, what I see is all sorts of "user error" out there.
And we also still don't know what percentage of the trailers being produced are using this brand of slide vs. others. Knowing how many actual units are in use and what the failure rate is would shed some more light on this whole subject.
Unfortunately all too often what we get on internet forums is, "I had a failure", or "I know a guy that had a failure"....and this eventually expands into, "that system or product is junk".
Sometimes maybe it is. Sometimes not.
I'm not willing to say this brand of slideout is 100% perfect. What I am trying to say is, without all the facts, all we are doing is making a guess.
To the OP, I go back to one of my original premises regarding RV'ing, and that is, "some assembly required", and "you need to enjoy tinkering".
Call the whole thing an industry with poor QC.....ok, I'll agree with that.....but for me personally, it's worth the hassle, it's worth having to fix a few things, because the pay-off more than makes up for it.
Others....well, not so much. It's why some folks try RV'ing, and then give it up in short order, and find something else to do with their time and money.
I've also owned boats ( still have one ), have raced and street ridden motorcycles ( still have three ), worked on two different car racing teams ( done with that ), and have shown horses ( still have and show horses ). All the things in life that have given me the most pleasure, have come with fairly steep "maintenance issues".
If you think maintaining your RV is work, try showing horses.
Loads of activities out there that are far more labor intensive than fixing a slide room in a trailer.
Buy tools. Get good at using them. Take the family camping. Have fun around the campfire. Life is short.
