I hate to be the odd man out on this one, but I bought a Do-All Aerial Assault and absolutly love it. I read these posts and decided to call Do-All before I bought, and I found their customer service to be great. They told me that they did have a re-design on the arm and the tray. The tray was originally going to be lexan, but they found it to be unsatisfactory, so they changed it to steel. I also asked about the bolts and washers, and they told me the bolts are not supposed to be counter sunk, that was in thier protype model, and with the steel tray, the washers are not needed. The arm is also what was causing the clays to break. They re-designed this after the first shipment and put a rubber strip down the arm with a dimple on the steel to make it unbendable, so that it will hit the clay in the perfect spot. They said anyone who has a lexan tray or first version arm, they will send them a brand new arm and tray. They told me these changes have already been made, and the traps in stores are the current ones. To be given all this information over the phone is not only very informative for me, but really shows the quality of customer service. I decided to buy one after talking to them, and sure enough the trap was the new one. This is the best trap I hae ever used. I shoot $5000 dollar auto traps on my father in laws farm, and will never use another one again. When they say it throws 100 yards they mean it. Quite, durable, and really powerful. Hope this helps you all like it helped me. I love this site and thanks for your posts.
