interesting... those pentax 110 lenses are already starting to get expensive on ebay... this should push them up further

And I am still not sure if this additional diaphragm has perhaps a negative influence on the lens performance.
The position of the diaphragm influences the distortion of a lens.

The original Pentax Auto 110 camera had the diaphragm in that position, so I hope they designed the optics with that in mind. Certainly with my waterhouse stops in that position, the lenses improve greatly over how they are wide open. The 18mm becomes sharp almost right into the corners. The 24mm is less good at the corners, even stopped-down, but there is some improvement at least.
I have ordered one, on the basis that I need to have different adaptors with different fixed apertures an at 30 quid each, it's too much.
I'll report how well it performs when it finally arrives

That's a good news, in my experience those lenses were not very good because they were only wide open. Stopped down a bit they may improve dramatically. Keep us posted

That's true.

Mine arrived today. I note that on some lenses, you have to set close-focus to get the lens on the first time. Then you need to focus out until lens stops before infinity. This is because the aperture mechanism is pushed too far in and lenses like the 18mm protrude into the camera body too far. With gentle but firm pressure, turn towards infinity so that is pushed the mechanism back in the mount (it is only pressed-in). Once infinity is achieved, you now have a fully working device.
There is more light-leak on this adaptor, so I cam going to fit a very small rubber O-ring in the rear of the adaptor. I'll let you know what size on Monday when I have tried some at work.

I think mine arrived today as well, just need to pick it up at the post office
Edit: Yes, I got it now!
Well, looks like this could work. I wished the aperture had some resistance or click stops. It's very loose and you don't relly know what f number your at. It's just a stick connected to the blades.
But h**l yeah, it's better than nothing!
I would start testing with my 18mm.

Ok, I would NOT recommend this adapter. I'm really disappointed, let me sum up why:
- It can't reach infinity focus at f/2.8 anymore, the construction is at least 1mm to long (I see a clear gap when pushing the adapters against each other)
- It can't really hit infinity when closing the aperture either
- Mount is to tight against the body
- Mount is to tight against the lens, I noticed a crack in the plastic of my 18mm after forcing it on 
- The aperture solution feels cheap and the stick doesn't have any resistance or click stops
- The stick looks "home made" and have scratches and a sharp edge
- There's no visual feedback of f-number
For $75 this is almost as fraud in my opinion. If someone else got a better copy, let me now!

Here's a comparison with 18mm lens:

I am in communication with them about the adaptor problems, which are mainly infinity focus and the stiffness fitting to camera. I'll let you know how it goes
But they seem keen to resolve the problems  I am happy to work with them on this, as I am aware that being an "early adopter" comes with this kind of problem sometimes

I might have been a little rough in my disappointments. I also wrote them, and maybe a little to hard 
I agree with you Graham, if they can sort out the infinity problem, that's enough for me. It's very close to work, just 1mm or so. Keep me updated

I have an update, the adapter works properly now!
I complained, and they sent me a new one, just perfect. They where also very nice and understanding.
I'll post some samples soon!
This is good news for the pentax 110 line-up
