The spring reverb on my amp has never worked properly, even after several repairs, so I needed a pedal for reverb. I wanted a versatile pedal to turn this need into an asset. So, instead of just spring reverb, I was looking for something with several types. The Polara has plenty of variety, doesn't sound too digital, and is a good price compared to similar quality pedals with this much to offer. My only complaint is that the writing is hard to read when selecting the reverb type, but after a little time with it, you'll remember what the dial is pointing to.
