Does anyone use speed camera detectors anymore?

Back in the day, speed camera detectors were pretty common and relatively cheap. With the constant change in camera technology and the fact that the UK roads are littered with all manner of fixed cameras, average speed cameras and camera vans, does anyone use detectors any longer and if so, have any recommendations.
Before all the trolls jump in, I’m not planning a Cannonball Run, I just want to avoid any issues while making reasonable progress on our roads!

My BMW M340i has the add on for fixed cameras and the head up display shows the speed limits and shows what the next limit is as you get close to it, so no excuse for getting caught. I guess that we have had the best years of motoring and now just have to trundle around in very capable cars, at motorway speed limits introduced 58 years ago!
