Made Measure Sliding Doors (London). How good is HAMMONDS?

Hi, I need advice regarding where to shop for floor-to-ceiling Sliding Doors wardrobes for our bedroom.
We looked at IKEA but the thing with Ikea, is the lack of flexibility with width and depth, when we have very specific maximum not to go over. Some looked great but I feel it will not meet our needs size wise.
Then we came across HAMMONDS (-uk.com), which was showcased at 'Next Home' Lakeside, they do a made to measure and installed service.
Does anybody know of them or used them? are they reliable? Good news or bad news? Quality or ****?
I am now being extra cautious as we had a difficult Kitchen experience with a company that was "too good to be true", so now doing my research first to avoid being disappointed or stressed.
thank you for your help on any feedback.
