I'm no expert but I have a CDA Fridge-freezer, washer-dryer, oven and hob in my flat and they have all been excellent. The oven in particular is one of the better ones I've used.
Expect all your friends to say "CDA? never heard of them"
I think there are some negative things on the MSE forum. Our kitchen man seems to think they are pretty good and said they are rebranded bosch units but I have also seen online that they rebrand other companies products as well.
had mine in for 8 years - fridge, dishwasher, washer, cooker etc, all abused daily since install, no issues at all, the stuff is really well made - I was told they use a lot of bosch components
