It seemed great..fairly easy to install and ok to travel with. HOWEVER, after just 2 1/2 weeks of use and one time traveling and putting back up, the plastic latch on one end doesn't work, which means that the rail WILL NOT STAY snug against the bed. Defeats the whole purpose. And, the top rail is leaning out slightly now, apparently from the hinge that folds up for travel (which was used properly). I am returning this an hoping to find something better. How hard is it to make a rail that is SAFE? Frustrating! Answer:

input:  Now, answer this question: Is this product review positive? Title: Is the bass sold seperately? Review: This unit seems to work OK out of the box and is pretty straight forward in its features. I haven't even bothered to check out all of it's functions because I don't need to go that far to know that I'm not keeping it. It sounds terrible. Yes, it's a cheap receiver and I knew that when I bought it, BUT...There are plenty of highs in the treble end, but on the bass end, turned to it's maximum, it sounds no better than the car-brand stereo in an automobile. There simply is no bass. I'm not expecting to shake the floor here, but there is very little to nothing in the lower registers. Bass guitars sound just like the electric guitars. Very disappointing.
