The SKS Race Blade Pro XL Stealth Series Mudguard Set has adjustability that is quick and easy to dial, and is impressively effective at keeping you dry both front and rear. They're not long enough if you ride with others, though.
With an exhaustive capability for adjustment, these mudguards work well across a range of road and cyclocross bikes – even those with disc brakes and aero forks. This versatility is what makes them a must-have.

The Pro XL Stealth Series (which is matt black instead of gloss) does a great job keeping spray and grit off your own kit and bike, but less so for anyone following, such as my partner who was hugging my wheel and complaining. I couldn't really ignore his moans when greeted with his mud-splattered face at the end of a ride...
I'd warn against using these on club rides – especially those with a mandatory mudguard rule (which is most I have come across).
But for solo dashes, for riders who own a range of bikes that may not have integrated mudguard mounts, these clip-on mud defenders are ideal. I found these a particularly useful addition to my race bike on mucky days.
Despite the temporary fitting, they're sturdy and don't rattle. That said, I did see some scuffs on the rear brake caliper on my rim brake bike and on the chain stays of my disc brake bike, so they obviously do move.
I would very much suggest adding helicopter tape, not only where the guards are mounted, but where the edge of the guard can hit the frame.
Suitable for tyre widths between 25mm and 32mm, the Pro XL is 565mm long at the front and 730mm at the rear. They don't stretch lower because the guards need to remain stable even with the non-permanent mounting system.

The initial set up, with four bolts on each side, is slightly fiddly to perfect. Two bolts adjust the angle while the other two adjust the length of the struts. It works well; you just need to set time aside to do it properly when first fitting to a bike.
(Top tip: instead of doing all the bolts on one side and then the other, I found it easier to get the guards symmetrical by doing the lower bolts on both sides, and then the upper ones.)
Once the hinges are set up, the quick release rubber straps allow the guards to be quickly removed and mounted. One pull on the rubber straps and they are off. There's no need to readjust when you remount them.
Price wise, the Crud Roadracer MK3 guards are considerably cheaper at £39.99 and are even quicker to put on, plus they take up to 38mm tyres across a wider range of widths. On the downside, they aren't as stable.
If you want fuller coverage, the SKS Raceblade Long set is available for the same £54.99 price as these (and not £45, as they were when we reviewed them in 2016).
The SKS Raceblade Pro XL Mudguard Set is very effective for solo riding, is very easy to mount/remove, and proves sturdy enough. The extensive adjustability means it is possible to set these up on a wide variety of bikes, too – just make sure to add some protective tape first.
Excellent, easy-to-use guards for solo riding, but not enough coverage for club runs

For clip-on temporary mudguards these provide excellent protection and, although they aren't the absolute quickest to set up, mounting is easy and is fast after the initial adjustments. They're sturdy and don't rub, either – so long as you're riding alone, they're excellent.
