Been interested in using a couple of riv nuts on a project spoiler not for outright strength more as locators using a riv nut to locate a bracket and keep it square to the spoiler. so not under too much stress.
Are they any good for moderate application and sure i read somewhere there are two types , one that expands and one that does not.
Any information / feedback on them being used appreciated.

I've used them to fit a rear door ladder to a Discovery, that's what came with the kit. I've used them for something else as I bought a tool to fit them but can't remember what, something on a horse trailer. Worked well for what I wanted and woudl use them again.
You can get different metal riv-nuts for different strengths.

you can get aluminium and steel, also countersunk or not, also serrated bodied or smooth bodies.
the larger aluminium and most steel nuts need a decent tool to fit them, not the £20 laser type, they'll just snap if you try and do them with those!

Used them quite a bit. Got a teng gun for not alot . I'd buy a reasonable quality one.
As for riv nuts don't buy cheap bulk curse word off ebay I buy mine from the local fasteners wholesaler. They are dirt cheap and good quality the eBay curse word I got a few years back are terrible.
Buy the ones which have a lip on the top it gives them something to compress ips against better. Never had an issue with them.

I use a lot of these at work, we use a pneumatic gun for ours though.
we use smooth bodied ones, although we also use flanged or hex shaped nutcerts. We use these in items that wI'll have a good bit of torque on the bolt in the nutcert. The theory is that it stops the nutcert from spinning.

I love rivnuts, they're the best invention ever. As has been said though, cheap insert tools are cheap for a reason. I snapped the handle in half on my last one and it's not as if I spend my days squeezing tennis balls. It was only cast ally and full of air bubbles. I "repaired" it with some steel plate and it's been fine since.
Another word of caution; aluminium nutserts are the easiest to pull but also the easiest to strip the thread out of, sometimes even with the insertion mandrel if you pull it too tight! And a rivnut is an utter PITA to remove once it's knackered, so take care and get it right first time. Also, Stainless ones obviously last best (plated steel rust eventually, especially if you use a fastener of a dissimilar metal that will electrolytically corrode the nutsert) BUT you will need arms like Popeye to pull anything above an M5 stainless rivnut with a cheapy "riveting tool" style apparatus. Or be crafty with a big G-clamp around the handles to wind it on. Pay £100 or more for the tool and it's a lot more possible, but that would only be worth it if you're going to use it a lot. For me it's one of those tools that once you have one you wonder how the hell you ever got by without one and use it all the time

I've got a pneumatic gun but they will set you back a few 100 quid 2nd hand so not affordable for a diyer really. Before I got that I had an 'A' shaped manual gun that doubled up as a pop rivet setting tool too. Think they are a tad more affordable and are pretty good even tho they are only a cheap Chinese brand.. (laser i think?)
Be sure to educate yourself on setting the tool up. Most of your difficulties will come from having it set wrong and either under crimping or over crimping (stripping) the insert.

Memfast make a setting tool that you don't need arms like the Hulk to use.
