Overall rating: 4.8 / 5 from 31 reviews.
It’s a good accessory to have at home and does the job. The only issue is that if your rack has 1-inch holes that aren't spaced closely together, the pin won't work; otherwise, I think it's excellent for the price

This leg extenstion LE06 is a perfict fit for my Mikolo M4 Smith Machine. It is easy to remove and set aside when not in use. This expands the capabilities of my setup. I am very pleased with this product and have recommended it to others.
Horacio B.5/5Verified
Very happy with the attachment. I have the 2x2 folding rack, the attachment fit perfectly and has minimal wiggle when loaded. Great addition to home gym and easy to store when not in use.
Daniel B.5/5Verified
I have the Mikolo m4 2.0. I don't think this was designed for this model but I made it work. The attachment itself is well worth the 💰.

Love it so far! It’s a must have
James B.5/5Verified
This attachment fits mt m4 original perfectly. It adds some function that I previously did not have. The added plyo box is great since you bc an use that for a number of exercises

Are there any other attachments for this model
Reeya R.5/5Verified
Can be a little wobbly. 6'1 with longer legs it doesn't quite fit right for leg curls.
Does leg extensions and hip thrusts great!
So-so for calf raises.
Do wish the ankle pad was a roller.
Setup is easy and over satisfied. Do need to figure out a wall mount solution for when it's not in use as it is pretty bulky.

Alicia A.5/5Verified
I'm in heaven. No more waiting at the gym for the rack. Still go with my wife for other things but my standard workouts I can do all from home. Space is limited so the fold up and options was the main seller.
I would definitely recommend. The construction and price is top notch. So many options, speedy delivery. Was here sooner than expected.Thanks again.
James C.5/5Verified
works decently, definitely a great space saver, still too used to a full size machine so it does feel a little wonky still. But it gets the job done!
Manuel S.3/5Verified
Fits rack. Awesome piece.
Jason A.5/5Verified
I'm completely satisfied with this attachment. Works well. I appreciate that the store contacted me to verify the measurements (compatibility with my cage) before shipping.

Pretty solid
Philip D.5/5Verified
This is an add on that adds a lot to the machine. It really is a must have. Just get it!
Amy L.5/5Verified
Exactly what I wanted
Troy H.5/5Verified
Works well.
Cory H.4/5Verified
It was super easy to set up and works great. Customer service was awesome helping me get my shipping address straight since I just moved and auto fill took over. Love it.
Jeff J.5/5Verified
Great piece used in all my leg days now
Bryson E.5/5Verified
Great add on to the rack I have. Can be difficult to use with hamstring curls but the leg extension works well as long as the box is 30in tall. Originally had a smaller box but mikolo was nice enough to correct this. Enjoying the extra equipment.
Christian M.4/5Verified
Great attachment and much needed for the gym
Bryson E.5/5Verified
Great piece of equipment. Very well made. Delivered fast.
Daniel C.5/5Verified
Love the attachment but it is a little more difficult for my wife who is 5 feet tall. Trying to find the right height for both the attachment and the box is a learning process.
Chris J.4/5Verified
Great

We needed something with a small footprint in our clinic/gym for knee isolation work. This works perfectly.
