Rubbish bit of kit-biggest mistake I have made buying it.
Its far too fragile for the rigours of daily life on the glass-it only gets brought out on special occasions
You so much as look at it and bits will fall off or worse-as has happened to me-the sections split or shear-and each new section is far too expensive.
Plus,the sections are always sticking together and they are the very devil to seperate if you are on your own.
I cant comment on the Gardiners modular as I dont have one,but,we do use 3 x clx of varying sizes and if they are anything to go by,their big 'un should be ok
