This works basically like most other tube style (atc) belay devices, with a small adjusment for giving slack to the leader. Plus it's auto-locking so you get the safety of a Grigri at a fraction of the cost and weight.

The Mammut Smart belay device is a unique assisted-brake device that has a lower weight and price point than the ever-popular Petzl GriGri. While this device may not be intuitive at first, it is pretty easy to lead belay smoothly once you've practiced a bit and is great for TR belaying. Lowering is pretty easy, but perhaps not as smooth as other devices. I would recommend this device for casual cragging. Overall, this is a great device for a belayer on a budget, but lacks the finer points of a GriGri.

This is a truly awesome belay device. I am a very light weight climber so most of the people I climb with out weigh me. I always found myself struggling to maintain good rope control and break control when I belayed with a traditional ATC. I heard a lot of good things about the GriGri but when I was first starting to climb I didn't want to spend that kind of money. So I decided to give this a try. First time using it I was astonished at how well it worked and how much easier belaying became for me.

I constantly get asked now wherever I am climbing "how do you like that device?" My response is always an instant "I LOVE IT". The only complaint I ever had about the Smart is the inability to top belay from an anchor. Because of that I have since upgraded to the Smart Alpine but can't stop singing the praises of the Mammut Smart devices.

I was a little apprehensive of buying the "Smart", as I know a lot of people who love the Gri Gri and similar devices. I thought you had to spend a lot of money to get an auto locking device, but I was wrong. This device works great, especially for the price. My wife, was very apprehensive of belaying me, used it and did a great job; she said it was very easy. The only issue I have ran into is the same as most of the other users, it is a little jerky when lowering a person and it is easy to short rope someone when they are leading a route. After a while you'll learn to find the sweet spot and get a good feel for it, just take some time to play with it on some warm up routes so you don't short rope your climber as their climbing a tough route.

I've shown this to many people who then went ahead and ordered one. I find it puts many (especially those new to lead-climbing) at ease when climbing, knowing they can count on the equipment to stop them.

Takes a bit of getting used to, but SO much better than a grigri... I've seen people say it doesn't always lock (or not completely), but I've never had it not lock on a fall. Highly recommeneded.

I've had it for a couple of months, it caught me on my first screamer. It worked, and my back wasn't sore. It doesn't feed as fast as an ATC or Figure 8 on lead climbing, but is awesome for Top rope. My wife refuses to use anything else.

It works like a grigri but is a third the price. Takes a few belays to find out how it works, but when you do it makes perfect since. Its really easy to let rope out when lead climbing but it just as easy to take rope in when you are top roping someone. If you want an assisted locking device that doesn't cost much and it light weight then buy this device.

While watching some videos of this device I've noticed people have issues keeping the break rope in the groove along the top of the horn and instead are having it come off and to the right (in right-handed belay situations). My question is: Is this an issue that will inhibit the device from locking if the person falls. And if so is it something that just becomes natural so it no longer is an issue? Or is the horn only used when letting them come down the wall/rapping.

Having the rope come off the horn at the bottom of the device is not a problem when belaying. The device still locks up perfectly. The horn is only really necessary to lower someone with the device. With out it, it would be very hard to lower someone because of the way the device locks up. So when lowering you just put the rope on the horn groove and use the horn to leverage the device out the locked position.

I've been using my Smart for close to a year and love it. It is a little tricky to use the first time you belay a lead climber (buy your partner some brew afterwards), but with a little practice, it's an amazing device. The only real drawback is not being able to repel with it. I saw a teaser photo of an "alpine" version - one that can belay with 2 ropes - a while ago. I wonder if it will ever be produced?

I absolutely love this piece of gear! Its the best auto assist on the market. Mammut really hit the bullseye when they designed the smart.

The smart is the ultimate single rope belay device out there (there's a two rope version coming out soon so you can use it to rap too). It feeds as fast as you can pull rope through a carabiner, it locks off instantly, and when the leader is hangdogging it doesn't kill your belay hand/arm cos it doesn't rely on you maintaining the friction. It naturally pinches the rope tight and doesn't slip.

Buy this over a grigri - its lighter, has no moving parts to get sand in and gum up, and feeding is so much easier. Although, like a grigri, you must spend some time learning how to use it. Just like a grigri, lowering and feeding are more involved than a non locking atc style tube device and the manual is your best friend here.

Check out the picture for its best work so far - 40 foot fall with no damage except to our psyches

Is the two rope version the "smart apline 8.9-10.5"?

This belay tool is not technically auto locking but it comes pretty close. if you normally use an ATC it will take you all of 30 seconds to get used to this device. makes for really smooth lowering. This coming spring they are releasing a double version that you can use for rappelling. You cannot beat this device for the price.

It worked alright but I didn't feel like it would do the job. My rope is a 10.2 that did feed very well and would slip through the device(we let go to test it's autolocking feature) with heavier climbers(190+). Other ropes that would lock up were hard to pull through the device. It did lock the rope better than an atc though. I prefer either standard atc or grigri.

Sorry you had that experience. I think maybe you where using the device improperly. If used correctly, the SMART will not slip when weight bearing. Its fool proof.

I'm just over 200 and this device catches me easily. No slippage. A little sensitive when lowering. Takes some getting use to.

This device is amazing. Although, I want to make something clear. THIS DEVICE DOES NOT AUTO-LOCK. Mammut designed the device to have rope slip to make a more dynamic belay. The device works by pinching the rope between the carabiner and the device. The amount of pinch on the rope can also depend on the carabiner used (use an HMS carabiner only). I would call this an assisted belay device. It helps you catch the fall and makes it more dynamic for a smooth fall. I choose this over any other device for leading. It's light, works on skinny ropes (I use a 9.4mm rope), not mechanical, easy to use, and did I say light. #1 rule with any belay device ... keep your hand on the brake strand ALWAYS.

I had some ideas about how this little thing would work and at first I was a bit let down with it. I just opted to use my friends grigri or even a normal atc just because I was more comfortable with those items. It turns out after a little practice this thing works great, I now use it over the other belay tools because it works so well. Give it some time and you just might like it.

The only issue I have had was at the gym using an old fat top rope, really hard to lower smoothly. Other wise have been using it outdoors since December with no issues. Great for belaying a leader. I like auto lockers, but think its too easy to keep your hand on the lowering lever (mistakes do happen no matter how experienced you think you are), no moving parts keeps this from happening, just keep your break hand on the rope. For thirty bucks it a great deal, if you dont like it chuck it on e-bay or something.

This thing is super. When it comes to the belaying function it really does lock up like a camming device (gri gri). On super thin ropes it may slip allitle but fine if you are always have your brake hand on. The 10.5 mm rope i generaly use however lock up on falls 99.99% of the time. It locks up good enough that it would easily stop a fall with the brake hand off the rope. (not that you should every do this). The only downfall is its limited function, belaying the leader, but it does it very well.

As Mammut says, not a true autolocker but its awfully close. I hardly have to do anything to hold a climber up. Lowering can for sure be jerky; it takes some practice. Like other reviewers have said - its a niche device, but I still like using this, especially when the climber is hangdogging, way more than using a tube device.

My friend has this device and I tried it out last weekend. It takes a little getting used to at first, but isn't too difficult to figure out. After using his, I went and bought one for myself because it was so affordable! Rapelling can be a little hard to get used to, but it's great for belaying, especially if you're small (like me) and belaying much larger people.
