Because "no tools" means cheap plastic tabs, and because there are no directions at all, plastic tabs break so unit cannot be returned

The tabs broke while putting the cover back on (sliding...not sure how they broke

The flimsy tabs can, and did, break easily

Its plastic so any real force can break tabs

Plastic tabs break easily while putting back together.

The first one arrived with a weak closure tab (I assume) and the whole case separated overnight.

The tabs on the plastic case do not line up well and I ended up bending them within a few hours, and attempting to straighten the bent tabs caused them to break off

The small tabs may break.

Cheap plastic tabs

It breaks off the tabs.

Very easy to break tabs that hold the enclosure together if you are not careful.

The reason I gave it a 4 star is the delicate locking tabs

There are 3 plastic tabs on each side and 2 on the connector end to secure lid to base.

I see how someone can break the tabs if they don't look first, and I see the argument that the rear foam pad makes it tight and angled when inserting a drive, but a thin knife blade let me compress the foam and get my drive in without worry

Despite repeated attempts I could not get the lid back on and in the process three of the cheap/flimsy plastic tabs broke.

The directions on opening the enclosure is rather difficult the first time so be careful not to break the tabs.

ˆt should work

It just works as you'd want it to.

Made of plastic but works as it’s supposed to.

Works as it's supposed to.

Worked exactly as I needed it to

Worked exactly as I needed to transfer data from my 1 TB HDD to my 128 GB SSD

it'd really suck if I lose that cable as I got nothing to replace it.

I have top out at a transfer speed of 300 M/B per sec with the same drive inside of them
