These are a great alternative to stacking wood or using the orange Lego blocks. They are very heavy duty and I expect them to perform well. The height seems perfect. I find the least extension I have to do on my stabilizers the more stable my setup is. I can’t wait to try these come camping season. I will be telling all of my camping buddies about these. I did see in the pictures that these can be stacked while in use. When stacked, there is good amount of rotation available between the two blocks. However, I assume that under weight the rotation would be non-existent.
