I had a Moultree 30gal tripod deer feeder I wasn't using, so I purchased a Moultree directional feeder motor and it has worked GREAT with Optimal Junior. I've experienced none of the clumping issues I've read here with Texas Hunters, even with my feeder facing west-southwest (direction of prevailing winds, especially during storms).

Based on that positive experience, last week I bought a 30gal Moultree directional feeder from Amazon Warehouse for about 55% normal price; the box had substantial water damage but the feeder itself was in great shape and even if I had to buy another directional motor I'd still be money ahead.

I'm a cheap bastage and my pond is 25 minutes from my house.
