Boltz CD racks?


I am considering purchasing a Boltz CD rack and am wondering if anyone has experience with these racks on berber carpets? They look like they could easily topple? I know they offer a wall mount stabilizing bar to ensure that this doesn't happen, but I would love to be able to use these without putting any holes in the walls! Any thoughts/experiences would be appreciatedv - thanks!

I've been using a well loaded 300 cd Boltz rack on berber carpet with no problem at all using only the feet. If I had kids that pulled on things or lived anyplace you could expect an earthquake, I'd use the wall fastener for additional security.
I ordered the CD600 rack on 2 different occasions. They both came with one bent, or curving side panel. I returned both.
I have two sets (330 & 660) of these racks on berber and loaded down they are very stable. However, they do offer the wall connector and larger feet. The larger feet may actually come with the newer stands. I have the feet but never used them because I didn't like how they looked.

Before I had it loaded with cds I did take the precaution of using some fishing line and a picture hanger nail that was nailed into where the studs were located. This secured it to the wall. After it got loaded about 2/3, I took the fishing line and nails off. Nail holes were easy to fill in too.
I've been using Boltz racks at home and in the office for about six years and have always used the wall bracket. In earthquake prone Los Angeles, I wouldn't feel safe without it.
Thanks for the responses! I think I will get them, is there a best place to purcahse from for price, or is it pretty much the same everywhere???
