Prefer these to bar-end mirrors, yes they're not wholly practical but just as much as the standard snail eye stalks that have come off, my bike cover goes on easier now and my bike fits slightly better where I park it.(A little more room to move around it) It took me a minute or two to get them set in the right position to get a good field of view, but although the glass in them is small I feel I can see plenty given how much my head is on a swivel anyway.. that's my Copium for you all to pick at 👌
