At the Las Vegas Open I meet the creator of the Squadmark system. I was impressed with the idea on how helpful they could be. I went on his site and pre-ordered a bunch then asked if I could do a review. He agreed.
I received my sample pack in the mail this weekend and started to put them through the paces.
They fit snugly on the 25mm and 32mm but the 40mm are a bit loose. They still stayed on but they slid a bit while the others were a tight fit.
I was able to put them on and take them off. This will allow me to swap them between my orks and tyrainds. It will also help when I want to change from 30 gaunts with fleshborers to 10 fleshborers and 20 devourers.
The one draw back i found is if you are not careful and don't slide the mark on and off you can easily snap off the marker tab. I am told was because it was a prototype and a 3D print. The actual product will be more flexible and the 40mm will be a tighter fit.
Each one had a magnet to affix to the base. They are easier to install than rare earth magnets while still staying in place. I can't tell you how many times I have used a rare earth magnet only to have the magnet pop off the base.
Overall, I like this product. I have already ordered a bunch for my termagants and orks. I plan on ordering more for my inceptors for transportation.
Check them out.
