In general, not asking about any specific device, is resin strong enough for long tern use?

I have tried two resin HT knock-offs. In both cases the resin was strong enough to stand up to everyday use without breaking, but after a while body heat would make the whole thing pliable enough that I could easily take it off.

I’ve had trouble with genuine HTs splitting at joints exactly the same way plastic does and the issue is I have no idea how to repair them. Had one replaced under guarantee by HT but when that split after 3 months they wouldn’t replace it again. It put me off paying extra for the real thing totally and I never have again. I’ve yet to find any knockoff that it resin, they’re all just plastic that I’ve bought but that’s actually better in my view because it can’t get too soft and it’s easy to work with if need be.

There are different materials, many of the knock offs aren't that great, either too brittle or become pliable bit some do a good job.

I've been locked in a genuine Cobra 60 to 70% of the last 2 years with no issues (month plus durations with breaks in between). It doesn't become pliable with body heat and cleans easily with a spray shower head.

I'm an active persons and it holds up great. I really like the lighter weight than metal.

A genuine Cobra is going to be much more durable than most plastic cages as the 3D printing makes it so there are no seam lines to split on.

From there is will depend on the material type and printing process used but that's really only going to matter if you're just getting the cheapest prints available or doing it yourself (I wouldn't trust a PLA material cage printed with FDM)

The Cobras especially (and my Evo and Sport cage) are made with Nylon PA12 which itself is a fairly durable material and done with the MJF process which each layer is bonded together at the same time instead of drawing lines of material
