I've used this maybe a dozen times, so this is more of a first impression review. I'm a road rider. I haven't swapped out my flat bag CO2 cartridges yet, but that's my intent.
So far I've been using it to inflate my tires at home. The instructions warn you to start the pump before attaching it to a partially inflated tire. It's a little awkward trying to connect the running pump, so I deflate the tires and start from near zero psi every time. It takes less than a minute to inflate a flat 32c road tire to exactly 60 PSI. The first few times I verified the accuracy of the pump's own measurement with my fancy digital gauge. It's spot on.
A number of people have noted that these pumps get very hot. At least with road tires and the shorter inflation time, that has not been my experience. Yes, it gets warm, but nothing close to hot. Battery charging time is super fast - seems like about an hour from a low battery state.
Overall this is a very nicely made!
I had been holding out on moving to wax. My new road bike came with a waxed chain and a bottle of the super secret drip wax. I was really impressed with how long the wax lasted vs lubes and topping off with the drip wax was as easy as lube. So I decided to switch my gravel and MTB to wax. Watched lots of "how to" videos and talked to others using wax. The Silica system seemed to make it easy to do. I have done 3 chains now with the system, no problems and can go about twice as long between lubes as I did with regular lubes. I use the strip chip when I do a full waxing which is much easier than cleaning a chain as it is just part of the waxing process. The hanging feature on the system is really convenient and easy to use. Chain stays noticeably cleaner too, besides being quieter. Not sure if it makes me faster as my new road bike is so much faster than my old but probably doesn't hurt.
This is a great tool to carry in your bike kit on those long rides where you may be out on your own or far from support. It's really small, but works like a charm if you have a spoke issue or need to do some road/trail-side repair work. These work really well and for the price you can't beat it. Easy to stash in a seatpack or tube roll. There multiple sizes of this tool so make sure you buy the one that fits your spokes. This is the same tool that I use when doing truing work in the stand.
Magicshine needs to explain how its products work. Both the instructions in the box and website are vague and unhelpful. It took scanning through YouTube videos and customer comments to uncover the secret to what is labeled as a 'transfer head' in the instruction manual. It's actually a screw-on Presta head to attach on the end of the short 'air tube" that is described as being helpful in tight situations. In my case, it is the only way to fill my tires successfully. The short, stubby rubber Presta adapter proved to be totally worthless because it couldn't create a complete seal on the valve. Now that I am squared away, the pump works great.
