ZOYOSPORTS Mini CO2 Inflator Compact Fietsbandenpomp voor racefietsen en mountainbikes CO2-cartridges niet inbegrepen

I just received this today. I had several bike tires lose a lot of air over these past few winter months including tires with both Presta and Schrader valves. I was able to easily screw the nozzle on to both types of valves to obtain a secure fitting. The inflator has a solid feel to it, and it accepted the CO2 cartridges releasing the contents properly.The head of this nozzle is a bit different than some of the tire inflators I have. In those, you have to flip the nozzle head depending on the type of tire valve you are inflating. On this one, you just have to insert the nozzle deeper to reach the Presta fitting. I like that difference.My other CO2 inflators have a lever to release the CO2 unlike this one where you press the button on the end to release the CO2. I think I like this method better, but only time will tell.In the photo attached, you can see in step #1 that it says, "Fix the pump to the bike frame by using the hex screws." There were no brackets or screws in the package even though the picture shows those. To be fair, the description page on Amazon does not mention included bracket or screws, but it is confusing to see the instructions mention said bracket and screws. I think the manufacturer should (1) include a bracket and hex screws or (2) explain that you can attach the pump to your frame with YOUR OWN bracket and screws.One thing that could make this a better deal is if the manufacturer included 1 or 2 extra rubber O-rings. My other inflators did, and I think this one should, too. You never know when you might lose one of these, or when one might go bad.All that said, for the price, I gave this a 5-star review. I've paid double for similar CO2 inflators that didn't work any better. As far as longevity...who knows? Hopefully, I'll never need to use it, but it's nice to have one of these on the trail. Just make sure you have some CO2 cartridges to go with it.

Very light weight. Very compact. Just so you are sure, this takes 16g threaded CO2 cartridges and those will add 10 bucks or more to the cost. But even then, it comes in at a good price. Materials are good and machining is very precise. I think they call it a pump, but it has a thumb valve on it to regulate gas flow so you can screw on the inflator and not release any gas until you press the button. A nice feature.
