I wanted to wait to say I had a chance to use them before writing the review so here it is. So far I've built with 3 out of 3, one worked and I don't have high hopes for the other 2. As a product, I love the idea of tiny little boards they stick in whatever is problematic. all work and none of the five work, if they can make something of that size that would work I would buy it, hopefully someone who has ever bought them besides me has better luck with them
