I have generally only used the clipsal ones in my house and the relatives ones because we started to do this place when PDL only had that ugly matt finish with the step-up for the switches available, and I quite like the clipsals. Which also have consistency in how they look, whereas the PDL 600s have had so many design revisions over the years that nothing matches when adding mode. But they seem stable enough with only the flushbox screws. I thought the end ones were only there if you are direct affixing the outlet which I have only ever done in the garage where it was going into plywood and was easier than trimming the hole for the flushbox to the screws without cutting the box to shreds.
I like the look of the PDL 600 series (I've changed our whole house to them). But the two quad outlets (horizontal/vertical) they don't match the look of the rest of their range.
They have those funny little switches, they look like they're on a surface mounted block and you can't get metal cover plates for them. I have two in our house: one in the laundry and one in a cupboard. I wouldn't have them in a prominent place.
The whole range of power sockets used to have the little switches on them. I dont like how the surround around the switch is different between the power and light switches, even tho the current lot all have the same rocker size on them.
Clipsal C2000 look exaclty the same now as they did when introduced, and the extra swtich on the power sockets doesnt look totally different which is what swung it for me. And that when I finally get around to doing cbus here they would be able to match too since im not getting the stupid modal LCD switches.
We have a PDL quad in our kitchen, installed in a new build. It has only 2 screws into the flimsy tin box yet it is rock solid and stable. And yes, it fits in a standard single flush box. What I don't like about them is they stand out a bit, and the covers are available in only white. Otherwise, works fine.
Silver spraypaint matches the satin aluminum plates that they sell as stainless quite well IME. I have several old HPM plates in the kitchen done and they are holding up ok. Some wear where the plug touches but that is covered by the plug.
kiwigander: To change it now would involve cutting ceramic tile - can be done but we'd rather not.
I had to do this recently in almost identical circumstances. I was reluctant to try and cut the tile on the wall because I thought it would be a PITA job doing it by hand and might crack the tile, etc.
However then remembered that I had a diamond/carbide-toothed blade for my jigsaw. Using that took me literally a couple of minutes cutting - the blade went through it like butter. Turned what I thought would be a tricky job into a really simple one - if you have the gear ...
Sometimes I just sit and think. Other times I just sit.
The outcome is that a new PDL 600 series double powerpoint has replaced the burnt one.
Unfortunately another device was too close to the double powerpoint on one side to allow its replacement by a quad.
We have cut tile in the past (Dremel tool works wonders) but were loth to do so here where, I believe, we no longer have spare tiles in case of a mishap. A moot point anyway, as it has been pointed out that a quad fits into the same cutout as a double.
