I waited until I had time to field test these blocks and associated kit to write this review and am happy to say that they worked perfectly to support the tent door. We used the setup multiple nights in the Sisters in a variety of conditions, including winds up to about 15 mph (I’d probably close the door above to a avoid stressing the zipper). It worked perfectly, opening up views of the stars and providing additional ventilation. Dealing with Gzila folks was seamless and they went the extra mile to get the product to me in time for my trip. Highly recommend this product, it’s totally worth the price. Thanks to Zayne and Gzila for an elegant solution to a known GFC need!
