Easy to use, sturdy built. It gets the job done. And if it ever breaks I'm getting a new one as there is no better option currently. Getting the reps in and profiting off the results should be considered more important than sparing equipment. Like you simply treat food as fuel, simply treat this one as a tool. Use it. If needed replace it. Still a better option than replacing parts of your body at some point in the future. Training Tip: Go as hard as you can on your Hip Flexors with reasonable load. They recover within a day, perhaps less than a day, so attack them as often as possible.

They slip off. Don’t work with Nike 270s. The base of your foot ends up being raised. Really not great.

I bought my first single Monkeyfeet(MF) early this spring after using it a fair bit and liking what it's enabled me to do, I ordered a second single MF a few minutes ago so I have a pair. what I like about it: 1. portable. can use it anywhere that has some hex dumbells. My MF also was compatible with my Olympic dumbbell handles. 2. gives me access to open chain, single joint, single limb/isolateral lower body training without downsides of machines(cost/resistance curve feeling off from limb length not matching up well with machine design/locked in to whatever gym has/machines are popular during peak hours so probability is high you'd be forced to have some form of a social interaction with another human to use the leg extension machine at 5:48pm in a commercial gym) 2A. can do single joint lower body isolation in different body positions that could possibly be more functional like using wall, squat rack, or TRX for support/balance combining hip flexion/knee extension/flexion using MF and triple extension isometric of the stance leg(seems like potential good way to develop strength/control on the farther side of ROM). standing unilateral hip extension isometric with a hamstring curl(gold standard of biceps femoris isolation) 3. let's you target different "rays" within a plane of motion similar to a cable. 4. MF uses minimal storage space/floor space. if you have enough space to lay down and do a snow angel on the floor with another 1-2ft of clearance around you you probably have enough space to do just about anything you can do with MF. 5. if you're embarrassed by how horrifyingly embarrassingly pathetically weak you are, you can use monkeyfeet to train in the privacy of your home/garage gym/basement/bedroom. I'm sure there are many more strengths. These are most apparent to me off the top of my head laying on couch in my post dinner vegetative food coma mental state. Things I didn't like: 1. Doesn't work with every type of dumbbell(I'm apparently horrifyingly embarrassingly pathetically weak and I should not be lifting weights in public training facilities where I can be seen by other people due to how horrifyingly pathetically embarrassingly weak I am) and was unable to find any 5lb or lighter dumbbells around the house or at the gym with wide enough handles to be compatible with MF 2. initially I bought a single MF to see if I would like it. I found that I did like MF a lot and was irritated by having to take it off and put it on the other foot. For some movements it's just easier/more time efficient to have a pair with one on each foot at the same time.

Seems like a useful exercise tool except for the plastic release tab that broke on my first use.

I wanted to like this product because it's a great idea. But it's a royal pain to use. A re-design is definitely in order. If not applied precisely it can cause ankle pain. It may not work with all shoes. Plus changing weights quickly is really not an option. You have to plan the weight swap and be balanced to complete it. It's not that you can't do it, it's just a pain to have to stop and mess around with this during a vigorous workout. If you have limited space, live in an apartment or perhaps on vacation these might be worth the effort. But if you have a good sized home gym as I do, Monkeyfeet will not likely enhance your workouts. Sometimes you buy a fitness product that looks like it would add to your workout then find out it doesn't. This was the case for me.

Terrible. Terrible. Terrible. Just a royal pain to try and use.

I wasted 200 euro on 2 of these. The idea of the product is great and the convenience of the ratchet strap is good. They also look pretty cool. That's as far as it goes though, the materials used are not fit for purpose. I was finding pieces of foam padding on the floor from the very first use. The rubber in the (plastic) gripping mechanism wears quickly and both units I purchased are useless after less than 3 months of use (1-2 times per week, ~6 sets each time). Ratchet mechanism broken on one and the other can no longer grip anything as the rubber detached from the 'claw'. They are rated to lift up to 160lbs (~70kg), and they can in theory hold that. In reality that would likely only work for vertical lift. Don't expect them to hold anything more than around 25kg if doing something like a leg-extension lieing on the floor as no matter how tight you ratchet the strap they'll be slipping to one side - creating a potentially dangerous rotational force on knees. These should be made from substantially more durable materials and the foot attachment needs considerable improvement.

Good product Sucks it costs so much. Literally tried multiple competitors and returned everyone. This works no questions asked for at least 50 lb dumbbells.
