The first thing that caught me was the fantastic price point (only $8 on Amazon). I love how it allows the sponge to fully air dry due to the wired bottom. I also like how it’s small, that way it does not get in the way of sink usage. Visually tidies the sink, that way I don’t lose my sponge in a sink full of dishes. 
My one complaint is that it doesn’t seem to stay suctioned on to sink, I usually find myself having to reattach it close to every time I take the sponge out or put it pack in. I also wish it was a little longer to hold sponge and drain plug, making for an even tidier sink. Overall if you are okay with faulty suction cups or plan to set it on the counter, I say go for this. Otherwise, I recommend finding one with better suction.
