Total Noob

I picked this up as I was getting into indoor climbing. It works great. It was super easy to figure out. After reading some reviews, I was nervous about it being a challenge to operate, but it really couldn't be easier.

Super Light-weight, Simple, Easy-to-use, Works As Designed

We've been using this as a belay device at the local climbing gym as well as on outdoor climbs. The Smart 2.0 is super light weight, very simple/easy to use, works great as a belay device, and has an auto catch built into the geometry. My family said they like using this device more than the Gri-Gri because of those previously mentioned reasons. Oh, it's also way cheaper than a Gri-Gri which is nice if people don't want to share devices. No complaints so far after using mine for over a year. I love lightweight simple gear that works. Mammut did it right with this device.

Love It

I have had the 1.0 for almost 10 years. 2.0 has the same quality feel and improved control allowing for better feed control when dealing with heavier weights and tricky situations

I Love This Belay Device!

Super simple to operate, uses physics and not mechanical devices, makes it easier to train yourself in high stress conditions, where tactile small motor skills can degrade. Would recommend to novice and experienced climbers.

Nice To Have

I like having my own gear, nice to have for climbing.

Great Lead-belay Device

Super handy gadget that I like best for lead belaying. The best at managing slack and reacts quick under a fall. Lowering is also pretty intuitive. Compared to an ATC it lacks the two-rope design for rappelling but its auto locking (practically auto locking) feature is a bonus. It’s also accepted by most gyms too, haven’t gotten denied yet at least. Simple, efficient and effective!

My favorite passive assisted belay device! The aesthetic of it is super nice, and doesn't feel like a toy like the Black Diamond Pilot.

Super easy to operate and the auto locking feature provides a little extra piece of mind. Works well for rock and ice climbing.

I Like This So Much, I Bought Two

This is my favorite single-pitch sport belay device because it feeds ultra fast yet auto blocked pretty fast as well and it's very light weight.

Super Useful Assisted-belay Device

The assisted lowering feature of this belay device is super useful for experienced belayers. This device offers a really smooth experience, but beware allowing its use by the inexperienced, as I’ve seen it help people form bad habits.

Cheaper Alternative To Bd Pilot

Decent assisted belay device. The lowering action isn't as smooth as the Black Diamond Pilot, which I prefer over the Smart. The Smart is a nice belay device for the price.

Favorite Simple Belay Devide

I have been using this device for a long while now and it is my go to for my regular gym sessions. I've used it extensively for lead and found it's very easy to feed out slack and it locks reasonably well. Won't be quite as good as the gri-gri or pinch for falls but I haven't found that to be an issue.

Excellent device for lead belay. Very easy to use. After trying the Petzl NEOX a few times, I still prefer the 2.0

Very Good For The Gym

If you want a belay device just for the gym and don’t want to splurge on a gri gri, this is the assisted belay device for you. It does take a bit to get used to, but it does have an extremely effective assisted braking system. I would recommend an arc however if you plan to do any outdoor climbing with it.

Device performs well, pays out clean and catches well skills with an ATC transfer well to this. If there is a large weight difference between the climber and belayer where the climber is the heavier it will be a bit jumpy when lowering in my experience. It takes a bit of learning to use this I would look up a video on how to operate it first. Overall a great cost effective alternative to a moving parts ABD.
