Sticky wicket!!
This product arrived as described with one exception. There is a label on the front with a sheer plastic covering which mostly comes off, however the paper and adhesive remaining defy every solvent known to man!!! It has been soaked (twice) in Goo Gone, twice in rubbing alcohol, once in stainless steel cleaner and three times in Dawn power wash.....It remains.... I'd go after it with a razor blade, but I don't want to scratch the stainless.

Looks beautiful! Easy to use.
Color: Transparent Grey
This bottle looks so nice on my sink. It keeps my sponge put away. The smoky color is pretty, but I can see how much soap is left inside. Compact design takes up little room on sink.

Good soap/sponge holder alternative
Color: White
Nice upgrade to the one I already had as it saves more space and holds a good amount of soap. It looks modern and fits my clean aesthetic. It’s a plastic material so it won’t rust easily. Overall it’s a good quality and has held up great in the past few months.

Leaks and cap is broken
Color: Transparent Grey, Color: Transparent Grey
I really like the looks and the idea. It leaks since day one, and I was too lazy to return and kept coping with it. Now the cap was broken and I cannot stand anymore. That's why you are seeing this review.

Very good all-around soap dispenser
Color: White
I tried out this soap dispenser as somebody who has just used the retail bottle with a free floating sponge for...decades. Right off the bat, what I most appreciate is the built-in sponge holder, eliminating the sponge living in a perpetual balance act on some portion of the sink, often taking a dive into the cold, murky water of a soaking dish. The holder fits a basic Scotch-Brite sponge/scour pad perfectly. The soap dispenser is much lighter than I assumed at first glance, and bigger than I thought it would be from the photos, but these turned out to be welcome attributes. It can hold nearly a full 24oz bottle of Dawn dishsoap. The color of the plastic is a little more off-white than the pictures, which was also welcome as it's less assuming on the kitchen sink. It looks like it has a bamboo base, or some other light colored wood that matches the off-white very well. I don't mean to get too deep on the appearances, but suffice to say, it's bland enough to blend in with a lot of different decors. The only reason for four stars is that the sponge holder has no way to drain, so over time, it's going to get pretty gross in there and require a clean out. However, the plastic seems pretty basic, so my hunch is that it would be easy to drill a few small holes at the bottom of the sponge holder to allow any accumulated liquid to drain out and prolong the period in between soap dispenser cleanouts. The price tag is a little steep at the time of this writing ($21.49). However, the return on that investment is the piece of mind of keeping the sponge in ONE place, always at the ready and being able to dispense a predictable amount of soap each time instead of flipping the cap of the retail bottle and inevitably getting a sinkful's worth of soap for a single coffee cup. Overall, I'm pretty pleased with this and would recommend it.
