Eh up 
My local wholesaler has started stocking Niglon Protego DBs... fitted one a couple of weeks ago, and fitting the next one next week. I really like them!
Positives (in rough order of importance for me personally):
Negatives:
As you can see from the picture, the main carcass has a bevelled lip for the lid, so when it's on, the lid and the back part are flush - rather than the lid stick out on the sides and top, as for most other ones. This - combined with the stiff DIN rail that doesn't offer any vertical movement - means the devices are always lined up with the lid aperture.
You can see the black grommet strip at the bottom of the picture - really chunky, fits a good few mm in from the edge.
I don't have any connection with Niglon (or my wholesaler) - I just like to share positive experiences, and sadly with electrical fittings these are quite rare!

My local wholesaler has started stocking Niglon Protego DBs... fitted one a couple of weeks ago, and fitting the next one next week. I really like them!
Positives (in rough order of importance for me personally):
- very reasonably priced (I always offer a "budget" brand and a "big name" brand to customers, unless there's a good reason not to)
- lid fits on really nicely, first time, every time
- you don't need to remove the bus bar to swap a device in or out
- mini-RCBOs with switched neutrals
- mechanically stiff DIN rail (centre support, even on fairly small DBs)
- single module T2 SPD slots straight onto the bus bar (like Wylex)
- fantastic grommet strip provided for rear-entry - will never come loose
- bi-directional devices available
- proper DIN rail blanks
- devices don't tend to lean when you torque them up
- only one manufacturer-applied sticker on the outside (under the lid, and it was stuck on straight) - hate it when the manufacturer can't even be bothered to stick their own badge on straight
- knock-outs are knocked out from the outside inwards
- looks alright
- tails gland (32mm) supplied
- captive lid screws
- torque stickers inside
Negatives:
- RCBOs and AFDDs only available up to 40A, so if you have a 10.8kW shower you're stuffed; higher-rated MCBs are available, but a separate enclosure for a high power shower won't look great for a newly-installed board
- although it has 32mm knock-outs top and bottom for the tails, the two side knock-outs are 40mm (may be a positive for some, e.g. if you have 50x50mm trunking) - 40mm tails glands are available, but are less common
- less widely available than other brands
