I fly an Alpha 300Q, Alpha 250Q, and two Alpha 110s. Until I bought the Transmitter and Tool Bag, my batteries, tools, spare parts, and MZ-12 were in ziplock baggies and different places. This Graupner bag now holds: eight 4s, six 3s, and 11 1s batteries, my MZ-12, tools (three pliers, screwdriver with two sets of bits, small bubble level, zip ties, Allen wrench set) and spare parts for my quads. The removal partitions are good dividers. The internal, largest compartment is divided to hold the MZ-12 and the six 3s and 11 1s batteries. The eight 4s all fit easily in the outside pocket. The Velcro closures and buckle all work very well. The bag is made of heavy cordura. The handle and shoulder strap are strong. Now, for me, all I need is to grab this bag and the quad I want to fly and I'm out the door. I can not attest to long-term durability. But, if material and fitment are indicative, this bag will suit my needs for a long time to come.
