Pros & Cons

Reasons to buy:

User Reviews

  • Proficient handling when lowering heavier people.
  • The handle is large enough to provide full control, while shedding down the weight.

  • Smaller than the original model, without sacrificing build quality.
  • Features a steel plate for protection.
  • The newer model is able to handle thinner ropes, up to 8.5mm.
  • Great for an experienced sport climber who needs an automatic belay device.
  • Lighter than the previous model.
  • Easy to switch modes from top rope to lead climbing.
  • Great choice for beginners.
  • Easy to give slack.

Expert Reviews

  • Able to use the belay device on solo climbs.
  • Features an ‘anti-panic’ feature, which stops the descent when the belayer pulls back too hard on the lowering handle.
  • The ability to switch between top rope and lead belaying makes it easier to take up and play out slack.
  • Optimal function on ropes 8.9-10.5mm, which are the most common diameters among climbers.
  • The high-use areas are formulated with stainless steel.
  • Able to set the spring tension in the cams by turning the plastic knob.
  • The steel plate reduces wear and enhances longevity.
  • Rated a 9/10 for ‘catch and bite’ rating.
  • The GriGri + has a high range for lowering compared to other similar models.
  • Smooth assisted braking device due to wide range of diameter acceptance.

Reasons NOT to buy:

User Reviews

  • Does not feed as well when lead belaying with a well-used rope.
  • If you pull back, the ‘panic’ feature will engage, even if you don’t mean for it to.
  • The safety features may not be necessary for advanced climbers.

Expert Reviews

  • The movement can take practice for it to become efficient and effortless.
  • Heavier than the GriGri 2.
  • Without practice, can be too slow or shaky when rappelling and lowering.
  • Feeding slack can be difficult for ropes thicker than 10mm or thinner than 9.2mm.
  • Only works on a single strand, meaning you will need to bring another device for double-strand rappels.


The Petzl GriGri + Belay Device is a top-of-the-line option for all levels of climbers. The ‘anti-panic’ feature sets this apart from other similar models, which after enough practice, will enhance the safety of the climber and the confidence in the belayer.
