Is it Too Risky Using 3rd Party Reverse Adapter?

When ordering something at Amazon, I needed to find something more to add to my order so it could qualify for free shipping, so I ordered a Fotodiox 10-LA-MR-PK-49 49MM reverse-mount adapter ring to mount a 50mm lens onto my K200d. I've never used a reverse-mount adapter before, but thought it would be a fun way to explore close-up shooting. Then, some time after placing my order, I read a review that warned about the adapter getting stuck on the camera. This was a little alarming, so I searched a bit more, including here on the forum, and saw where some others have had similar problems.

Now I'm not sure that I should risk trying this adapter. I don't want to do damage to the camera or the lens. Am I being too alarmist? If so, any tips on avoiding trouble? I'm sorry if the answer to this seems obvious, but I didn't find an answer when performing a forum search, though my searching strategy might have been flawed. Thanks for any advice. If I have to just trash the adapter, I'd rather have wasted about four dollars than ruin a camera or lens.

The adapters that typically get stuck are the infinity focusing M42 mount adapters, they have a little spring clip to hold them in the mount since the lock pin can't be used.

The reverse mount adapters are made like the non-infinity focusing adapters, they use the lock pin like normal and shouldn't get stuck. The only way I could see it getting stuck is if you somehow over rotate it in the mount, which is unlikely. I've got a cheap no-name reverse adapter and have never had a problem. I also have cheap infinity focusing M42 adapters, though I modified them to eliminate problems.

A third party reverse adapter should not be overly risky.
