We bought these to install a 1400x700 bath and overall we were really impressed with the fixing mechanism and installation.
The fixing mechanism looks a bit weird initially but when installed leaves the bath really secure (There is no risk of it moving)
When the got the unit in position it was easy enough for us to level off and tweak the install and after getting in and out of the unit a few times it is clear it isn't moving anywhere any time soon.
