BTO (Bursa Trim Ortomotiv) flush sliding windows reviews/ info

[Cornishvan]

Hi all, I am looking to replace my leaky malfunctioning original OEM sliding rear windows. A well regarded local converter in my neck of the woods has given me a price for fitting a flush sliding Window by a company called BTO. Has anybody had any experience with fitting these, I.e. do they leak or are they fit and forget?

Hello, can I ask the converter company ?
I am based in South Wales and currently need to replace one of mine, they are all BTO and after one to match the tint, cannot find a supplier anywhere!
It’s the sliding window that’s leaking looking for a solid pane
Thanks
