The Good: Great quality of tools and features within the mini multitool, solid craftsmanship, durable, very compact.
The Bad: For certain fixes the short tool lengths can be pain
As with most Lezyne products this multitool has really great build quality, is very durable and just overall feels very solid. The Rap 13 unit features most of the popular and important tools that would be required trail side and they come together in a very small and compact little unit. If you are looking for something compact and tough I would strongly recommend this one, there are no flimsy plastic parts on this multitool thus you get a durable tough product.
The one major pain point (although that's what you get with a compact unit) is that in certain fixes the tools on this multitool are too short. If you are just tightening your stem it works great but if you get into the bolts on your calipers or front derailleur/ or anything that is in a tight space the short length of the tools on this this unit can cause some issues as you have to constantly remove the unit when you try to tighten or loosen bolts and re position it to continue turning bolts just because there is not enough space for the Allen keys to move around without hitting something.
So if you are considering this tool you just have to be aware that the compact little package does come with a caveat and its bulk can be a bit of a pain when working in tight quarters (such as rear shock area).
