had a couple of issues with the quality, the retainer hole for one of the screws was not tapped so it could not be assembled, I fixed this myself so no major worries there - also the outward opening spring doors like everyone else notes are a really bad design - birds are not stupid or weak - they can open these, so unless you want to lose your birds clip them closed! Also the springs themselves had sharp protrusions that required bending back to avoid injury, also the welding on the wires also had sharp edges that required filing smooth.

In short, cheap and economical but definitely not for novices as it requires handy work to make safe and secure, DO NOT buy unless you can fix minor issues. If you can and accept that you will have to do a bit of work then the cheap cost is definitely worth it.
