I first used Aegis stations after a professional baited a rental house. He left the stations and a key and I re-baited them later. I liked them so much I bought six more. The bait can mount horizontally on two bars (4 baits total or five if you cut one in half) and they are very secure if you bend the bars at the 90 degree corner to open up the rod. That way it really locks in when the cover locks. If you mount three baits vertically, each sits on its own rod and a thin plastic plate holds the ends of the rods secure to prevent bait "snatching." I prefer the horizontal bar setup -and you can order extra bars. I have used bot the black and clear cover models. After three years in the AZ sun, the oldest stations are still pliable and function great. Hosing them out is all that is necessary to get ready for more bait.
The plastic case is heavy duty and should last a long time. The size is a little larger than the brand I had before. And, the vertical and horizontal wire for the bait blocks are not real secure. However, due to the sturdiness of the case, I give these bait stations five stars.
