Curiosity got the better of me and I ordered one to have a look at. I'll report back when I receive it, if anyone is interested (in several weeks, I suppose). I'm not planning to fit it any time soon, but the redundancy afforded by there being two brakes on a bicycle would reduce my anxiety about one of them being potentially untrustworthy. I always keep in mind the fact that one brake could fail at any time anyway, and ride accordingly, so my life wouldn't be in peril should the part fracture or something (if I ever got around to fitting it, that is).

I'd rather remove the back brake altogether and jam my feet down to stop. No way would I trust a Heath Robinson bodge like that.

What happens when the adapter mounting clips fail? I don't want to know

Look away now then @the_mikey....
There will be an awful soiling of underwear and a crash.
Personally neither appeal to me so I'm.going to keep my £1.70 in my pocket.

For that price you should have ordered several. Just to see how many brakes you could fit to one wheel.

I guess I was robbed as I spent considerably more than £2 on this disc conversion bracket for my bike.

Theres a difference between that and the earlier links. Yours is bolted on, I'd suggest it's more comparable to a post mount adaptor. I'd still not do it and stick to whatever the frame was designed for though.

The ones in the links are a clamp arrangement around the stay - liable to move under braking and be difficult to align without rubbing so would need adjusting frequently. Relying on clamping with a braking component just seems a really bad idea.

Do not all brakes rely on clamping?
I tend to agree with some of the negative comments in the above posts, but would like to evaluate it for myself, which can't be done properly by viewing a photograph.
Some things that don't seem like a good idea turn out to be fine. Can you imagine the derision with which the first heavier-than-air flying machine was greeted, for example? Or the helicopter ejector-seat... no, hang-on, that was a bad idea! :-)
I can live with the £1.70 research budget, BTW.

Whats wrong with sideways if enough elevation

The helicopter ejector seat was invented in the early nineties by Professor Piehead (a cartoon character from Vis comic). Apparently it was 'Another Partial Success!'.
I've no idea why that has stuck in my head for several decades. I'd love to see that cartoon again, though.
(Maybe if you wrote into Viz they'd pass your suggestion on to Dr Piehead himself!)

It's the clamping onto the seat stay I don't like, but for £1.70? - why not.
Pedantic engineer point - brakes don't work by clamping, they work on the friction between the two surfaces. Squeezing the brakes produces a fixed force on the pads as it's a mechanical thing (brake lever/pad movement). The effect they have depends on the pad/disc friction, clean and dry works better than oily.

Most motorcycle rear brakes sit on a mount that has the wheel spindle go through it and then it uses a torque arm and is not bolted, but is normally just a slot on the holder that locates on a bung on the inside of the swinging arm.

Don't Kamov Ka 50's blow their rotors off when the ejection seat is activated?
Or do they just do that at random, in the great Soviet tradition?
Here's another thought on automation.

Back on topic, I sort of see this bracket, used for purpose, like automato #2. Unsuccessful and potentially messy.
