'Smart weight locks' that no longer lock :(

These are no longer locking, letting the weights slide right down the bar (and no doubt, eventually right off and into my head).

Was expecting these to come as a pair

Was expecting to order as a pair so I put in quantity x2 to use on two barbells. Disappointing that the image clearly shows two with the order..... Or have I just not been sent the second pair?

Useful only for very light lifting

the grip is slowly getting worse. Once i was doing hammercurls with 6kg on each side and the lock just gave up and all the weight fell down, narrowly missing my foot. Now i have a hole in my floor, but at least not a hole in my foot.

Bad quality

Broke under a week of use

Smart Lock 28mm

Slight flimsy feel but does the job. There are better ones on Ebay.

Doesn’t fit 28mm bars

Brought these to save the effort of spin locks during lockdown home workouts These do not fit any of my 28mm standard bars at all. Fall straight off and even go onto the bar without opening/loosing the lock Wish i read the reviews beforehand.


So quick and easy to use - far easier than metal clamps

Does the job perfectly

Good quality, does the job

I've been waiting for these to come in since march 2020 (non lockdown related but post part related). Always sold out. I've only just been able to order them successfully from this joke of a site. £3.50 but £5.99 for delivery?? is this a joke? not only that, parcel force 'attempted delivery' 3 days later (3 days when I spend this amount on delivery?? aye okay..) they didn't, I waited in for these all day. Not only that they said they'd posted a card through the door. again...lied. Frustrating when I really wanted these for my barbell. anyways, delivery prices is extortion and clearly using the lockdown BS for their profit


These have been excellent so far

Nice product but need a stronger grip. Ok up to rated weight but need a bigger brother
