Instapak Quick RT #10 Cushioning Foam Packing and Shipping Solution (15" x 18") 2 PACK

Worked for what i needed it to, put these in my computer case (Mid tower took both bags to fully secure) and moved to kansas on a bus, computer fully survived the journey and these kept everything in place.

For my first time using this foam expander, it was pretty simple. Just follow some simple directions and you'll get it. The one thing I'd be careful about is the temperature; since the foam expands rapidly, it generates a lot of heat. I'd advise to let the foam rest for a bit after you're done packing. Nevertheless, great product!

Pretty simple; it gets the job done for pretty cheap!

Thanks Jay's Two Cents for sending me here. They have a good instructional video on packing a PC with these. I did 2 with tempered glass and both survived. Remove the GPU.

Easy to use as long as you know how you want things to be situated before you activate it.

I thought all negative reviews of this product would be user error and failure to follow the instructions, but apparently not. My pack did not inflate more than halfway before the sealing material could no longer expand and fill the pack. It blocked itself off before it could inflate.Product arrived at destination undamaged, though. I added more of my own packing material around the interior of the PC case. I'm sure this failure of a pack did more than nothing, but it would have been nice if it actually filled all the way.

It did not completely inflate. I might have used it incorrectly, thats why I'm giving a 3 star review. I think after you pop the second chemical pouch, you are supposed to spread it with your hands to get it to completely inflate, but it doesnt tell you that in the directions. I used it for a computer build I was shipping. I probably wont purchase these again, unless the price lowers.
