I haven't had any issues with my SXK boro's but I might just be lucky, the glass is quite hard to move at first but it gets easier with time....
I notice the top of the glass isn't quite square, I'm not sure if that's a fault or if it's designed that way to help the glass slide over the ring... I'm always careful to install the glass the same way just in case one end is smoother and better than the other ...
Those that have issues with the ring bunching, maybe try rounding off the top edge of the glass with some fine wet and dry sandpaper or a knife sharpening stone.., a nail file or emery board might be adequate... Smoothing that top edge might be enough to stop the ring catching and bunching....
