no net time saving

It's probably more a function of the amount of crap the brakes are exposed to than the price point, but I am tempted to look for another one of these to replace the 5 on the back, which seems far more inclined to stick. It was worsened by the rim the rear brake was being asked to grab being somewhat concaved, it being the old wheel I replaced back in May but which I thought I might get away with using for winter tyres to save at least one tyre-fitting operation. Unfortunately, the grabbiness varied so much within each wheel-rotation that it was difficult to not lock the wheel, which I would prefer to avoid with these tyres to avoid ripping out the studs.
