To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Product exactly as pictured (3 racks, S-M-L), works with all cable diameter/materials I've tried so far, sticks well to surface thanks to built-in adhesive band. Soft-touch-plastic-like material feels nice and keeps an appropriately low profile.
Adhesive band could be provided separately like similar items, which would make it easier to remove and repurpose the cord holders.
These stick to any surface, and don't leave a lot of residue when you have to remove them. They still stick at least one more time after removal (I haven't removed any twice yet). My only complaint is that I wish the inner part of the "loops" for the cords was non-stick, I really can't slide the cords through it. I have to lift the cord out, move it to where I want it, and then replace it in the holder. It's easy to take the cords in and out, though, which is nice. They actually look decent, and they take up only minimal space compared to some of the cord organizers on the market.
I bought these to manage the rat nest of cables that have resulted from my work-from-home setup, which involves both a personal laptop and a work laptop and two 27" monitors, plus a keyboard, all connected through a 2x2 KVM switch. They attached nicely to the edge of my monitor stand, and they definitely tamed the plethora of cables coming out from the switch at all angles. The only reasoin I didn't give them 5 stars is because many of my cables (mostly the HDMIs) are quite thick, and the openings at the tops of the cable channels are rather narrow, which forced me to use a pair of needle-nosed pliers to bend the openings a bit to tuck the cables in. Once thus arranged, however, they spring right back and have held the cables very securely, and the adhesive seems strong as well, which I hope means that they'll stay put long term.
TL;DR: Good and satisfying cable management solution, but if you have thicker cables it requires a bit of fiddling.
I mean... it's a nice looking solution to a common problem. I placed mine on the side of my desk. Cords run up, through this, then flop over onto my desk to be plugged in when my laptop is present. It does OK, but now and then (=at least once a week) cords fall out and have to be picked up and placed back into this doohickey.
