I don’t like it
It does feed smoother if you do not hold the device while you belay. So you hold onto the break strand with hand and the climbers end with the other. But if you like to hold the device with your thumb and index finger and clasp the break strand with middle, ring and pinky finger than purchasing the neox does not make any sense. With this form of belay it does not feet any smoother. And taking up slack is somehow more difficult than with the grigri. And it’s heaver. And it’s not great for multipitch. One you can’t belay off of the anchor and with the added chores of multi-pitching…lets just say i like having the extra sense of security of the grigri.

This is THE Belay Device
- Familiarity:
- I've used it several times
This device is sooooo sick. Lead belaying with the neox is SMOOTH AS BUTTER. It leaves virtually no chance of short roping your climber and still provides a quick catch when they whip. 10/10, 5 stars, Grade A+.. its seriously the best!

This belay device feels really good, its super smooth feeding rope to a lead climber. The future is now.

THE device for lead climbing
- Familiarity:
- I've used it several times
- Height:

I LOVE this device. I cannot even explain to you how much of an improvement this device is for lead belaying over the traditional GriGri. I am a smaller woman and often am belaying someone over my height/weight, and the ability to feed without short roping is KEY. The device still catches like a beast AND you still have the control over lowering. If you mostly lead climb/belay this device is a MUST.

Best Lead Belaying Device
- Familiarity:
- I've used it several times
The Neox is a phenomenal upgrade from the Grigri for lead belaying. The feeding is so smooth that you'd have to fight giving slack when the climber is clipping. Falls catch the exact same as the Grigri. I was worried that the lowering process would be too sensitive and I was pleasantly surprised with the friction. That being said, if you have a heavier climber, you will have to watch your lower a bit more than the grigri, but the difference wasn't huge like a Revo. Probably the one thing to take into consideration for buying this is that this device is really specialized for lead belaying on, generally, single pitches. My Grigri or Pinch is still preferred for a crew that might TR.
