Using these helmet mirrors for years on every new helmet. Even though Garmin Varia tail light tells me when vehicle aproaching from the rear, a quick head tilt gives me visual confirmation of what's comming, and how close they may be when passing, while still seeing the road ahead. Also, when riding in a paceline, can keep track of riders behind, without losing site of rider in front.
Must be careful when adjusting angle so as not to detach from helmet. After securing in place with included adhesive disc, I seal the edges with silicone glue/sealer.
I'm lucky enough to have a few bikes. I have a saddle bag with what I need in it. Just having mounts on my bikes allows me to quickly move the bag from bike to bike.
I haven't tested other E-pumps but you can't go wrong with this one! I've only used it a couple of times to test it (no road flats yet!!) but if feels to be high quality. Size and weight seems to be the same as others that buddies have. Screen is large and readable. Battery seems to hold a charge (tested over a couple of months) and I believe you could get 2-3 inflations of a road tire, as advertised. I have a Magicshine radar taillight (about 8 months old) and couldn't be happier with it, so had a lot of confidence in this brand before purchasing. And with all their products, you can't beat the price!
