Rated 4 out of 5 by from This device makes climbing safer The MegaJul is the only belay/rappel device I use now. I can hold a leader sport dogging like a GriGri, rappel with single or double ropes it in autolock mode or smooth mode with an autoblock backup, belay two people following at the same time, ascent a rope with it if necessary - and best of all it provides a backup to the brake hand in case I get knocked by a falling rock or get slammed into the wall and drop the brake rope. Also, unlike many autolocking devices, the MegaJul builds good belay habits because you keep your brake hand on the rope at all times. Doing all these things used to require multiple devices - the MegaJul does it all in a single unit that's as light as the smallest basic belay devices.

Rated 5 out of 5 by from Does everything I've long been a fan of auto-blocking belay devices like the ATC-Guide and Reverso for belaying the follower on multi-pitch routes. Likewise, auto-locking styles like the Gri-Gri are great for belaying a leader – but for long routes they're heavy, and only feed a single strand, making rappels tricky (do-able, but requires some shenanigans). Last summer I got the Mega Jul as a gift, and love it. It's superlight, and the simple design is brilliant – it basically does the same as an ATC, ATC-Guide, and Gri-Gri all in one. It's still essential to keep hold of the brake strand when belaying a leader, just in case, and pairing it with the right size/type of 'biner makes a big difference in how smoothly it works. A unique feature – probably my favorite – is that you can do normal rappels (two ropes, no shenanigans) with it in locking mode. Takes some practice to rap smoothly, but key is that it locks if you let go of the rope – a built-in backup for the sketchiest part of climbing. The Mega Jul's versatility means it isn't idiot-proof – the fact that it does all of those things could be slightly confusing at first. So, maybe not ideal for beginners. For example, in one configuration it will automatically lock, but in another it won't. Obviously important to know the difference. Fortunately, it ain't rocket surgery. As with any tool, you need to learn how to use it. But once you do, it's an incredibly versatile and safe belay/rappel device.

Rated 5 out of 5 by from Will blows your friend's Grigri out of the water I saw a video demonstration of this belay device and immediately fell in love. I was previously using a Mammut Smart Belay and carrying a Reverso for rapping and belaying my second. Now I have one belay device that does EVERYTHING. It even makes espressos!! And since you're carrying less gear you will be sending projects at least 2 grades harder! This device is a miracle. But seriously, I only wish my belayer would buy one of these. The only people who wouldn't use the MegaJul are either stuck in the habit of feeding slack the way you normally would with an ATC style tube belay because they're "old school" or because they can't bring themselves to admit that this $35 modified tube is more functional than their overweight $100 Grigri (Sorry Petzle fans).

Rated 5 out of 5 by from Behold, the new gold standard. "It's the Gri-TC!" one astute climber declared, when he saw the best of both worlds in action in this one, remarkable belay-rappel device by Edelrid. Tipping the scales at 62 grams and made of stainless steel rather than of aluminum--which tends to hold onto heat longer, and is far less durable--the Mega Jul solves the critical problem of today's spring-loaded and auto-locking belay devices: when a belayer is forced to pay out lots of rope--and rapidly--these devices work too well, often binding up, resulting in an erratic and "short-roped" belay at a key moment for both the safety, and the composure of the leader. In normal mode, the Mega Jul allows the belayer to throw as much rope as quickly as the leader needs it, with the fluid ease of a tube-style device. If the leader should come off, however, the Mega Jul's unique design automatically checks the fall the way you'd expect a spring-loaded, or auto-locking device to. Finally, it's the Edelrid solution to the age-old conundrum: it's no longer necessary to bring an auto-assist device for belaying, and another, tube-style, for descending--just the Mega Jul. Belay features: In normal mode, belay a leader with all the benefits of a tube-style device, but with the security of an auto-locking device. The Mega Jul will auto-lock, too, when providing a sling-shot, top-rope belay. In plaquette, or guide mode, bring up a second--or, a third--belaying directly off the anchor by reorienting the device. Flip the device into tube-mode to enjoy the same, unrestricted rope control you'd expect in a belay plate, or tube. Rappel features: When used in tube-mode, the Mega Jul behaves like any other plate or tube-style device; the climber must maintain control of one--or both--brake strands. Though it's never a bad idea to take other precautions, too--like knotting the end(s) of the rope--when rappelling in normal mode, whether descending double-stranded or single, the Mega Jul functions as an auto-block, backing up the system in case of loss of control, or an unexpected need to go hands-free. Things to keep in mind: The Mega Jul is made of steel, which is a bit harder than aluminum, and with heavy, frequent use, the device will score the rod stock of your HMS belay carabiner. The marks are merely cosmetic, and are the result of the interaction between the two dissimilar metals. Though the Mega Jul's rope diameter tolerance, according to Edelrid, includes ropes up to 10.5 millimeters, the functional range--in my own experience--seems slightly smaller. For the best results, try to pair the Mega Jul with ropes <9.8-10.0mm. All belay devices have their nuances; anytime I upgrade to new hardware, I not only take my time in mastering its use, but I also try and familiarize my partners with its proper handling. The Mega Jul's a game-changer, both in terms of safety and versatility; everyone ought to know how to use one!

Rated 4 out of 5 by from Makes belay less a chore You can find comfort in the fact that Elderid design is build for climbers, and works perfectly. Nothing beats the statement "functioned as designed". further explanation is unmeasurable to what you get for actual use. A perfect try/ but scenario

Rated 3 out of 5 by from Meh... It works OK I really wanted to like this thing but it sits in my bag unused because I find the Petzl Reverso 4 MUCH smoother. I love the autoblocking function but it is very difficult to lower smoothly on this thing. I like it for the occasional alpine belay and could see where it would be nice on multipitch but for sport climbing and top roping, I find it to be more trouble than it is worth. It also gives me a sore thumb from constantly having to pull up on the release to get it to lower.

Rated 5 out of 5 by from Nifty Overall I found the transition to using this device after using a reverso/guide quite simple. Lowering a climber isn't too tricky, but I still struggle to produce a quick or smooth rappel. In guide mode, the device is even smoother than the BD or Petzl version because there are no "teeth" to drag the rope through.

Rated 5 out of 5 by from 1/3 the weight and 1/3 the price of a Gri-gri! Purchased the MegaJul over two months ago and I am extremely satisfied with its performance thus far! It does take a little playing with to get used to, especially when lead belaying, but it is super smooth and the assisted breaking feature is super reliable! I cant wait to use it for top belay on the north shore! The large selling points of this belay device are its ease of use, its weight, and its price. Plus it does everything that your clunky, expensive Gri-Gri will do, in addition to double rope raps!

On Mountain project forum their are a few pictures of the thumb look cable on this device pulling out. Do you know if their has been any update to this device recently, like a 2nd model that fixes this issue?
