Strengths: quality product
every tool i need on the go
Weaknesses: not recommended for the weight weenie
This multi tool is a good one if you are very inclined to do work on the trail on you bicycle yourself. It has more than enough options for any quick fix any day out on the trail. I carry it in my camelbak everywhere i ride. I ordered a mail order bicycle and assembled it with only this one tool. It is a bigger beefier option as a weight weenie would not want to carry this with them. I would recommend this to anyone looking for a good multi tool.
Weaknesses: The T25 Torx does not fit very well into disc brake bolts. When your Torx doesn't fit well the corners will break. I bought some Craftsman Torx drivers and they fit much better, less play between the tool and the bolts.
I think the Alien design is pretty slick, but as with most multi-tools, they cannot replace real tools.

Great tool has saved me many times. Only gripe I have are that its made with plastic with conserves weight, but makes it weaker. I is heavy, but I knew it was when I bought it.

Strengths: Nice design, compact size and quality materials.
Weaknesses: At 290g this thing is WAY too heavy.
I could easily do without all the box wrenches - I don't even have a single hex nut on my bike! Buy something smaller and with only the tools you need for half the weight of this. If that multi-tool doesn't include a chain-breaker, then get a Park CT-5 Mini-Brute Chain Tool (72g).

Strengths: contains about all the tools you could need for a trail-side repair
Weaknesses: heavy & bulky
I've been happy with this tool so far. It has only been used a few times (which is what you want for an emergency tool!) but each time it had just the tool for the job. I would like to see Topeak include the frame mounting bracket with the tool & case. It is so large that the Alien II and a spare tube fill my saddle bag.

Strengths: Wide selection of useful tools, very well built with (almost) industry-grade materials and quality.
I used my Minoura for almost 17 years with complete satisfaction, but sometimes I found its range of tools not enough. I found Alien II a good way to upgrade, and ordered on on eBay. It's far more useful than any other similar pruduct I've ever seen in local stores (mostly with poor quality and/or too narrow selection of tools and/or extremly high price). It has only one real weekness: weight. If you can make this "deal", I mean, a lot of features with very good quality versus the extra weight, I recommend this product.
Strengths: it has lots of tools, pretty solid, good design
Weaknesses: has some completley obsolete trail-tools (like a bleed nut wrench: when are you gonna bleed your brakes on the trail, right?), it rusted and I have never needed to use more than 5-6 of the tools on it. it's overkill
its a good tool if you are hard on bikes, but other than that, don't get one. if you want something to use as a tool to fix the basic problems you usually occur on the trail or if you aren't an excellent bike mech, go for something smaller. it will mean less weight and less space taken up, and I guarantee you, you will not use all the tools on it.

Strengths: Wow, this thing has everything! Chain breaker, all the allen keys, wrenches, everything! And it all fits in the nice carrying case, which has a pocket for my smart links!
Weaknesses: Can't find anything yet. I guess you can say it's heavy, but for what it does and is meant for, I can't complain.
Had a recent trip at Downieville including 3 flats and a torn tire. Unfortunetly, I forgot my tire levers until I noticed this bad boy had two of them! Chain got jammed inbetween my granny and middle ring too, so I had to unbolt my granny to get it out after splitting my chain two minutes before! This tool did everything in an emergency time fashion with ease. I love it so much, Im buying another to put in my road seat bag.
