1. First you can see our tent canopy is inflated separately. So if there is some risks that the leg is broken we can just replace that one. Each legs has a in&out valve and safe valve, the safe valve is helping you to release some air when you inflate too much. 2. Second our material is 0.3mm thickness TPU, using double stich sewing and wear resistant material. The canopy has the waterproof edge part which will avoid rain to come in... 3. Our printing material is oxford cloth, it is waterproof, fireproof and UV proof. Which are good for unpredictable weather like big sun snowy and rainy. 4. Finally once you inflated the tent it can stand without any blower to support. It can lasts about 20 days without any leakage. That is the biggest advantages.
