Personally, I’m currently keeping my hands off everything that comes from JustSim. You can almost quantify a failure rate of 100%. This is also reflected in the addon list. But everyone has to decide for themselves.
I concur with what both these users said regarding JustSim. I had a lot of their scenery and frankly liked it a lot, but once (I can’t remember which) Sim Update rendered them unusable, they never came back and fixed any of them so they all CTD for me (at least too many to trust them or go thru and try each one again).
Right now I’m trying to find other vendors’ replacements of those I had and unfortunately I can’t most of them. They haven’t updated anything on Facebook either to indicate they even care. I just don’t trust them now.
I can also offer a solid recommendation for LVFR. They’re good about updating. They have nice renditions of all the airports they’ve done. Easily in my top 5 vendors for quality.
I have every airport they do except SCEL (I’ll get it once we have a good study level long haul like PMDG 777). I also use their AREX products but Ammon the fence about global traffic upgrades and probably not interested in jetways.
