Question: Any problem using this with a Pentax flash???
Document: This tool really works. I have a Pentax Af360FGZ flash that fits on it fine. After I screw the tightening mechanism enough to secure my flash shoe (not too tight), then I use the securement latch on my flash to secure it also (as I do on my camera). This device can be mounted on my tripod and my flash stands using the adjustable mounting piece on the bottom.
I've used this mount bracket for a few months now and it has worked out very well. With a Yongnuo flash and CowboyStudio umbrella in it, it holds whatever position I tighten the screws down on for hours at a time. The only problem that I've had is that the groove mount that the flash sits in is fairly wobbly. I'm not sure why CowboyStudio couldn't have made it all more solid, but it hasn't failed me yet. It's just a little scary every time I let go of the flash.
And, I did it in a way different from what you might expect. The bracket comes with a round plastic and metal adjustment nut that sits between the hotshoe and bracket. If you screw it onto the bracket all the way and the screw the hotshoe down everything is pretty much tight and lines up pretty well. The problem is the umbrella screw and the hotshoe screw are both on the same side.
flimsy, seems to need some TLC to hold the flash in place on the light stand.
Practice with your equipment and ensure that the 500 dollar flash unit is going to  be supported with that umbrella and the 20 dollar adapter before you let it alone.
Ordered product for portrait photography. Product is sturdy and just what I was looking for in an off the camera mount for my external flash unit and umbrella. Great price!
I have used this a few times and have found no fault in the bracket. It holds the umbrella and flash well, doesn't slip, and seems very well built. Great price too.
This  is a great bracket for umbrella and/or flash I will use it for my off camera flash and like the umbrellas I must wait to get more of these. Probably three or four.
This is a perfect attachment for an old tripod a friend gave me. I was able to securely attach it to the tripod and then mount my flash on it. All supplied hardware is included for an easy setup and usage. I then purchased an umbrella for some added softness.
What can I say about this product? It does what it's supposed to! It seems pretty sturdy so far, the threads haven't been stripped, however the hotshoe clamp has fallen off and I can't find it anywhere... it's ok, though I can just use the mounting foot that the flash came with!
Answer: I don't have any more Pentax flashes but they have a standardized shoe like Nikon, I'm sure it would work. Sony, maybe not, but Pentax should be fine
