Rated 4 out of 5 by from great tool I commute to work, shop, exercise, and have fun on my bike. On and off the road. This is a great tool, you can repair about 80% of any problems that might happen with your bike. I've used this tool many times to help others on the trails. Has a handy little storage place for extra chain pins, doesn't come with them unfortunately. Unfortunately, it's flippin' heavy, clunky, and a lot of the tools don't lock in place. It has a very sharp knife that locks, but that gets in the way of using the tire levers. You don't want to open the knife when you're trying to get a tire off, but if you leave it closed it gets in the way.

Rated 4 out of 5 by from Weighed cost versus utility. I prefer full sized tools but there are times when I know I'm going to have cleaned out my panniers (I have six panniers or bags on my bike), and I'm going to forget to put the tools back in. When that happens, I decided that the painful (for me) expense of [$] for this multi-tool would pay for itself later. Well, today it did. I didn't realize that many of my allen wrenches were missing from my set and I had to use the Alien to work on the front derailleur. I also have already used the knife, yes, that's right I used the knife. This would make a good gift for a fellow cyclist.

Rated 4 out of 5 by from A must have for extended rides This tool always comes with me on any of my longer rides. It has just about every tool you could want on the road or trail for everything from minor adjustments to emergency repairs. The tools are so handy that I sometimes find myself reaching for my Alien in the garage too, rather than digging through the tool box. The only con I've found is that despite the separating halves (which certainly helps) the tool can still sometimes be a little too clunky or short to reach where you need it to. 99% of the time though, it gets the job done.

Rated 4 out of 5 by from Heavy and bulky, but full-featured The tool takes up a lot of space in the saddle bag, but it's got tons of features. I use it with the mountain bike, where weight and bulk aren't big issues. Unfortunately, the plastic tab that "locks" the two halves together broke, so I have two little multi-tools. (More metal, less plastic, please!) No huge deal, though, because I keep it in the nylon storage pouch anyway.

Rated 2 out of 5 by from Big, bulky, inefficient My ideal multi-tool has what I need to get me home in a pinch - it will deal with the weird situations I encounter on the side of the road/trail. At the same time, I don't want to tow a bucket of parts and a full size tool kit. The Alien has an abundance of tools, and as such is big and heavy. I weighed it at home and it came in at over 12 oz. (3/4 lb.) with the case. For a multi-tool, that's a lot. Now don't get me wrong - I don't have a problem with this thing's weight per se. If it's useful to me, I'll carry it. The problem is that at least half of the tools on this aren't really necessary in an emergency. These are peace of mind tools that you will probably never use, use so infrequently that they're not worth carrying, or use on the trail simply because they are there rather than to get you home and make the repair later with normally sized tools. Sure, it'll get you out of a bind, but so would a tool that's half as big. The other thing that really irritates me about the Alien is that the tire levers are built in to the tool. I break levers from time to time - they're cheap, that's normal. Having them integrated in to something that I plan on keeping for a long time makes me uneasy. This integration also interferes with how easy they are to use. I don't want to be stuck on the side of the road/trail fiddling with tire levers that have tools stuck to the bottom, especially when one of those tools is a knife. My last issue - and this is really an issue with all bike multi-tools - is its lack of pliers. Pliers are one of the most versatile, valuable tools for solving weird problems. I know a lot of cyclists carry pliers or a camp tool in addition to their multi-tool. Why someone doesn't integrate the two is beyond me. I do think this would be a good tool for people living in cramped quarters (like college students living in dorms) who might make small adjustments from time to time but not have or want a normal sized tool kit. In that case it could sit in a drawer and the size/inefficiency wouldn't be a big deal.

Rated 3 out of 5 by from Chain breaker bent Just bought this and on my first attempt to use the chain breaker the pin bent, will probably return it for something a little more stout. It's a little bulky but it is pretty complete.

Rated 5 out of 5 by from Great gadget, great gift Great tool, has everything you need. This was perfect for long bike trips, when you need to repair on the road. I recieved it as a gift, and use it constantly. Since then, I've purchased additional ones to give to others as gifts.

Rated 5 out of 5 by from Worth its weight I've had the original for almost a decade, but it recently jumped from my bag during a ride; can't complain i even reach for it for household repairs. I'll be getting a new one very soon
