You can add a bunch of plates through the spotter arms for added stability. Taller things can go on the top of course. I will be returning them for a refund as soon as I get home. I have been looking for a shower speaker for a long time, now I found the iFox speaker, the wait was worth it, as the saying goes the best things come to those people who wait. Solidly but and heavy. I had originally bought a four tier spice organizer from this same seller but unfortunately had to return it as my cabinets were slightly to small. You can control it with simple taps and hooks up to bluetooth easily. Those earbuds are so good and worth the money! I have to say for the price around $25 you can?t beat them! The touch controls are simple, but definitely intuitive.
