My builder was installing a new shower door for me and we chose Frontline's APRIL shower doors, we bought it through Travis Perkins.
When it arrived, the door was scratched and the little rollers which is to close the shower door was faulty. So my builder took it back and asked for a replacement which came 3 days later. When he opened the package, one of the the rollers was already loose and was stuck in the corner of the door, he tried to put it back but couldn't. So it went back for another replacement. Third one came and the rollers were all present so he went ahead and installed it, the last task according to the manual was to adjust the rollers. When he tried, the whole assembly fell off to the back of the frame, he had to disassemble the whole thing to take it out and found the assembly to be unrepairable. So he took it back and ask for a replacement this time one without rollers.
A big company like Frontline sure had some design and production problems, so any of you when considering a shower door, get one with magnetic strips, do not opt for those using rollers.
