probably not for very heavy things, but....

i use this to carry rice, and I have no complaints. My concern is that the handle would break if there were very heavy things put in. I would buy again.

A little flimsy/wobbly, but gets the job done just fine!

Well made and ended up finding use for, but not intended use, because this is BIG and heavy, do not want be lifting it much.

I'm using this to hold something other than a smartphone and that item is somewhat bulkier.  Additionally, it must hold the rectangular object parallel to the ground, which is not really the expected application.  It does seem work for my unusual needs, but I think the plastic "clamping" of the carrier may not be tight enough for transport vibrations.  I will likely have to replace the "phone carrier" portion of the product with something sturdier that mounts to the standard "camera mount" screw.  The base of the unit, seems quite adequate.  So, I'm generally pleased considering I'm using it in a somewhat unusual fashion.

Heavier than expected, but works like it should.

Feels like most of the moving parts will break without much use, but until they do... 4 stars at this price.

While this product is useful, it isn't very heavy weight - rather chintzy.  It does hold my jackets and the 2nd one I bought (at the same time I bought the 1st) holds my turtlenecks (I don't have enough closet space)... but, they are a little wobbly.  I would have liked to have something that was a bit sturdier, but there is no way to tell by the description.

As advertised, but I was expecting something a little less flimsy.

NOT TOO STRONG, BUT STILL A GOOD PRODUCT..
PD: I RECEIVED AN DISCOUNT FOR AN HONEST REVIEW

works fine now, but I don't know how sturdy it will turn out to be

Possibly not as heavy duty as some would expect.  But it met my expectations and works great.

I didn't expect the plastic to be as flimsy.  Perhaps a little more thickness would prevent the shelves to bend (particularly towards the middle).  Anyhow, they're not that bad if you're not hauling anything heavy.

This product was not exactly what I expected because there is no weight to it however, it gets the job done..

Not solid enough, but if it's out of reach, no worries.

I've used them in sand bags for shooting rests, but sometimes I would prefer a little more weight, but I can't fault the product since they weren't designed for this purpose.

Odd beast. Works of course. Who would have thought you could turn a vibrating multi-tool into a coping saw? It's OK, I guess. But, it's pretty delicate. Don't expect to be doing "industrial strength" stuff with this adaptor. It's fine for that occational light duty task though.

not the sturdiest of metals, but this is not an everyday cookie cutter. It will do just fine.
