There's not much to say about this item. As can be seen in the pic, it's a solid piece of metal with six tools along the edges. Does an effective job at basic roadside repairs, although you won't have every size allen bolt you need, particularly if you're on the road with your kids and their bikes along with your own. Also the length of the item can get in the way of screwing or unscrewing a bolt - meaning you might only be able to turn the bolt 20 degrees at a time. That being said it's a quality, reliable, simple tool and I expect it will last a lifetime.
When my wife saw this, she said, "Really?", "Joeblow?". I told her we needed to get past that and look at the quality build and ease of use this pump provides. It is easy to use with the dual valve capability, she's a Schrader person, I'm a Presta kinda guy. The multi-tip attached with no problems and stayed put. I just installed new tires/tubes on one of my bikes and this pumped them up from flat to 60psi in like 9 or 10 pumps. In my 50+ years of serious cycling, I've owned a few floor pumps but mostly used hand pumps, so this is a huge upgrade for me. The large gauge is nice, I don't need one that large but I may as my eyes start to fail. After filling the tires, I checked them with two different gauges and they were all within a pound or so. Some of the reviews complained about the plastic base, all I can say is that it is strong and solid. I hope to have another 10-15 years of serious riding ahead of me and I totally expect this to be my last pump purchase. I would buy again but don't think I'll have to.
Replaced a similar product that could not be removed from its holder without loosening bolts (!). Appears to function well, but I have not had to use it in the denouement (flat tubeless). Hope not to use it.
