Works great!
This is the best dishwashing spray I have ever used. A bit pricey, but lasts a very long time. One spray on a sponge works!

The perfect dish soap!
Great product! Arrived well boxed and packaged. My dishes are clean, the soap smells great, and the spray package works perfectly. Great product!

Skip this soap
The spray bottle design is awful. The nozzle shoots liquid everywhere and it takes 3 pumps to even become foam. As far as the soap itself, while it does clean food off dishes, the suds disappear quickly so you end up using way more than standard brands. The lemon scent is nice.

Powerful foaming spray
Love the powerful jet of foam this gives on my dishes.
Small leak in the bag, but I just tightened the screw thing and it fixed it.

SLS free
I am looking forward to receiving this product to go with their SLS free hand soap, and to have this bottle on display in my kitchen. Since the spray nozzle seems to get decent reviews I'm considering buying the 6 bottle set.
