Why We Like The Smart 2.0 Belay Package

The Smart 2.0 Package increases safety and support when giving our partner a catch. As we pull in and feed out slack, the carabiner's safety gate prevents it from cross-loading, while the intuitive belay device operates according to the tube principle yet works with the 'biner to block the rope when the route spits your partner off.

Counter Intuitive, hard to intruct to new people.

Grabed this in hopes of giving it to my belay partner who was inexperienced, after tinkering around with it myself, I found it rather difficult to use in a safe manner without a lot of experience. Furthermore, when I went to climb the wall and had others instructing my belly partner on how to use this device, they were unable to help due to the unpopular nature of this product. With enough experience, this thing actually is rather nice for an easy belay experience, but I'd rather either go with grigri or an ATC, this thing just makes for a weird middle ground. I wouldn't recommend taking it in any Alpine setting. The carabiner is nice though 👍

Great piece of gear

Familiarity:
I've used it once or twice and have initial impressions

I bought the pink one because it's pretty haha, but it works great! I'm used to using a BD Pilot belay device so I wanted to try this one since it works similarly. Still getting used to it, but it's great for top rope belaying and will be great for lead belaying too once I get the hang of feeding slack out of it. I like that it has assisted braking.

Best belay device on the market

Super easy and intuitive, very easy to translate from ATC and I prefer it to grigri because of how it works better with thinner ropes. I use it for lead belaying mostly and I must say the device can get noticeably hot when lowering someone 40-50 pounds heavier. I always recommend learning on ATC but if you want a more comfortable and safer option to upgrade too this is the best option on the market.

Quality Device

Love the ease of use and love that it comes in pink! Bought two, one for a backup to keep at work and one back up for personal climbs. I find passive devices like this to be more intuitive for belaying and this one is super easy to pick up for first timers.

One of my favorite devices of all time!

Super comfortable to use! very safe, never dropped or slipped. I wish Mammut would make a smart Alpine 2 like they did with the first smart. Super light and compact, would highly recommend as a cheaper alternative to Grigri.

New favorite belay device.

I wanted to try out a new device after using a gri gri for a while now. The smart 2.0 is much lighter and very smooth to use. This device really shines for me when lead belaying it's the smoothest assisted brake device you can get and not to mention at an awesome price point. 10/10 recommend.

Great for single pitch sport climbing or when working a route

Easy to use once, like everything new, you figure it out, intuitive never the less. Holds well and is nice to have piece of mind if anything happens of for neubies. Assistance for belayer when working a route puts ATC style devices to shame! Also still worked on icy and wet ropes where the Grigri struggles.

Smart belay device

Love the smart belay device. I have used my friends for the past year and thought that it was about time I got one for myself. Feels great in the hand and easy to get used to. The carabiner that comes in the package isn't the best though. Personally I like a carabiner that I can use for multiple functions. This one has just one use which it does very well but in my personal opinion I would rather have more uses to it.
