This review will help people that want to buy make up their mind. We bought a corsair 350 in 2014. The delivery came, and we paid Dunster House extra to build the cabin. A few months later we noticed that the logs were disconnecting, part of the roof was coming apart, and one of the side panels was falling. After complaining, they decided to come back and put things right. The defects were amended, although the gutter always had a problem, and some of the logs did not match perfectly. At the time they let me sign a piece of paper that said on checking the work everything was ok. I signed in good faith although I am not an expert, so for me was good enough. Wrong. This year the logs are disconnected. They are the same logs of 2014 so I am aware of the fact that was not rectified properly in 2014 has contributed heavily to the fault. We have gaps of 2 cm across the all cabin. I have contacted the customer service team in the after-sale department. They told me this is not covered by the guarantee even though the cabin is covered for 10 years. We were also told that they do not offer the service of building the cabin anymore and I have an idea why. The after-sale service is actually pretty awful. You can only talk to them by email. I have asked them to phone to discuss the matter but they have refused. They have sent us some u tube videos to solve the problem. I have followed the u-tube videos to try to solve it. Up to now, it has not made a bit of difference but I was given a timeline. Once the timeline has expired and I have done everything possible if the problem is not solved, I will ask a carpenter to fix it and bill Dunster House. Please think carefully before buying from this company. Their cabins look fantastic on the brochure and they probably are if they are fixed properly, but our experience was awful and expensive from the start and once you buy you are on your own
