Have also used some in the UK a few years ago, and the UX was much worse. Usually slow user interface, some of them are even speaking to ask you to put down every single article... might be fine as tutorial, but so slow if you actually use them regularly.
Sainsburys annoys me every time. The slightest delay in putting the scanned item on the scale and it starts nagging you, very loudly. I avoid them as far as possible. M&S is the same - nice place to shop in, but self checkout is unpleasant.
However, they are much less annoying here. I assume it's all just parameters that are tuned to local requirements.

I’m in an Eastern European country and have the same machines in some supermarkets, no scales, no gates just scan the stuff and go.
That would’ve been unimaginable 15-30 years ago. Theft and violent crime rates were sky high. Having your home broken into or even getting mugged in broad daylight wasn’t that special (these days you have a high chance of getting a story in a national newspaper at least if you get mugged).
Of course it’s far from perfect and there are other issues that need to be solved. However under the right circumstances significant change is possible even during relatively short timeframes.
This article mentions the south of England but they’ve rolled it out country-wide since:
The touch screens for the ones in Manor are terrible OTH, they seem to require a very precise light touch, but not too light, I find it strange that the more "upmarket" Manor has the worst ones.
I scan everything beforehand with their device, then head to the self-checkout with a shopping cart full of items (already put into bags), I scan the QR code there and I pay. Done.
The whole operation is like 20 seconds max, and it's how it should be.
Using self checkout in the UK, US or in Italy is a nightmare. First of all, they don't trust you by default so you have to weight everything (this operation takes on average 10s per item). Half of the time the systems are broken (in terms of UX) and you need to do things in a specific order (e.g: you can't scan a rewards card with the other items - you have to do it BEFORE even starting to scan the products).
The basic assumption is "trust the customer". Thus, the self-checkout devices don't have the annoying "you must weight the article you just scanned".
You just scan them one by one, add them to your bag, pay at the end, and that's it. Sometimes (it happens to me around 1/year) you get a random search, which is not that bad as they just randomly scan ~10 articles from your cart and it just beeps (i guess ?) if they're not paid for in your receipt.
