Very easy to use
I like the clamps for fitting the weight to the bar.
Not very durable / hardy.
Smart weight lock works very well and very happy
Good stuff
All sports products are with best quality & very reasonably priced.... awesome place for sports range.
Best lock I have ever used it's very good very secured for dummbell I loved It
This lock is suitable only for Decathlon 28mm rods. I am used so many locks for so many size rods.I thinks this is a perfect rod and perfect lock... I am happy of this product.. thanks u guys
Great quality
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
Good quality in normal coat
I asked for old style nuts for locks and got suggestions from decathlon’s employee to use this lock but it’s too loose. Wasted my money on this.

Nice product
These are sooo bad, such a bad thing to sell, considering these might mess you up a lot if weights fall at wrong time.
