I can't think of specific problems with them. Maybe I've had problems
like Adam, but spread over years I don't remember. Just keep in mind
their use case. If you're doing simple routing at a site that's moving
~100mb, then they're probably fine. If you want full throughput of a
couple 1G 820C radio, you'd probably want something else (when routing,
they would probably L2 just fine). I've always used them as routers.

Like Nate, we had a few of them and had no problems. Then we deployed
25 or 30 of them to small sites. Most of the time they just sit there
and run. Over the past few years we've just had a few scattered
instances where we had to reboot them when traffic wouldn't move to
one port.
There's one at a hub site with several backhauls plugged into
it....that one actually needed a reboot a couple of times so we
replaced it. Then it needed a reboot again a couple more times since
then.
These events are scattered over 3-4 years so I'm not saying they're
UN-reliable, they're just not critical infrastructure level of reliable.

I have some opinions on this.
1) Yes they're cheap.
2) They run ROS, so if a newb comes along who doesn't realize that
this is switch hardware and it has a crappy CPU, then that newb might
try to make firewall rules and VPN tunnels and other such router
functionality in the config. That will be a mistake because the CPU
is weak and you will get crappy performance. Leave it as an L2
switch and the performance is perfectly fine.
3) Configuring L2 functions on the switch menu in ROS is obtuse.
I've messed with VLAN's, port isolation, and port mirroring. It's
all strangely difficult to understand and use.
4) I've had them just decide one day that they'll stop forwarding
packets to one or more interfaces and then "fixed" them with a
reboot. I've also had them sit there and do their thing as a basic
managed switch for several years with no issue.
I would not use them for critical infrastructure anymore, but a
switch with a small form factor and extended operating temperature
spec generally costs several times what the CRS costs so I'd still
consider it for the right circumstance. I can't tell you what the
right circumstance is. That's your call.

We usually use the lower end HP procurve switches, we have had zero
problems with them over the years, but now theyre office connect and
seem that all the 24 port ones are going deep instead of 10 inches.
The CRS stuff is 1/2 to 1/3 the cost of comparable HP switches.
Have any of you degenerates used these very much and stayed with
them? We route with mikrotiks so we are aware of the mikrotik funky
stuff, the cost offsets those
