Product review (1 stars): The issue is the very poor quality of the plastic "box"
The issue is the very poor quality of the plastic "box". The plastic is so thin and flimsy that the lid does not easily fit in place - putting it on while there is water inside is nearly impossible and very inconvenient. There is so much flash to be removed that you should plan to spend an hour or more with an Xacto knife to fix it. I've had products similar to this before and found them useful, but the poor quality makes this model unacceptable.
