Works well if 2 parts are held together.

Am making hundreds of these balls for a project at work.  Fill bottom tray completely full then slowly push top tray on.  Some will spout out top but that is ok.  If a few have 1/8 to 1/4 " air on top is ok as ice will expand.  But try to get most full.  Wrap two thick rubber bands around to hold them together as balls freeze.  While still together run each side under hot water briefly.  Hold upside down, twist and bang against sink to break off all chunks that have frozen on top from overflow.  Then open up tray and twist each piece to get balls out.
Works quite well this way.  But would be great if there were clips to hold the two pieces together, and if the plastic was softer and more bendable when frozen.

If you unscrew it, take note of how the parts go together.  I put one part back backwards and of course it didn't work.  Once I fixed it, this works ok s great.

It worked relatively well, but you cannot really move it once it is together. It falls apart if you move it.

Works fine. Just realize that the legs will all be stuck together, so you'll constantly be separating them but that's the nature of the product.

This has worked well, although you have to be very careful when removing the side to use it with the horizontal tripod slots as they can catch and start to separate the tablet.

I liked it because it came in three separate parts so you could use one two or three parts as needed.

A little difficult to put together and it has an extra piece not identified in the instructions. That said, it works as advertised and is convenient.

Functional, but the wood splits easily during installation, and the preassembled pieces were not all connected securely.  Had to improvise a little, but now that it's set up and covered, it does the job.

works fine, except the corner piece is gonna need glued. I'd be more worried if I had it hanging.

The part is fine, but the picture clearly shows 2 pieces and I only received 1.  If you read the text closely only 1 is mentioned, but the picture and description do not work well together and are unclear.

Parts can be a little delicate. May encounter either stiff or loose joint situation.

Works great.  Slight assembly issue, holder became loose quickly.

You have to be careful when separating the perforated parts as they like to tear where they shouldn't.  Otherwise, works good.  Once put together, pretty sturdy for cardboard.

The protection is adequate, but it's a two part case.  I had to use Gorilla Glue to hold both sections together.  Maybe I missed something...

It isn't a terrible product and while the parts are organized the instructions could be better. It took a long time to put together you definitely need two people to do it.

Once it's together it does what it's supposed to do.  When putting it together, you have to screw some parts together and the predrilled hole at the top didn't line up correctly.  I ended up using my drill to make the hole bigger to fix the issue.

A little challenging to put together at first, but once you figure it out it is not a problem. However this is a two person job.
