I’d like to get some more feedback on this.
User reviews?
There are a lot of recent threads on this subject. (what works and what doesn’t)
Searched it but didn’t find much, specifically in direct sunlight.
You just got to sift through “those threads”, but I’m sure someone will chime in on your post. 
In my experience it dose not work. The stingray smears the glass really bad. I think the stingray is all hype and not very practical. I had two of them and both broke. Unger is not very helpful with warranty claims either.
I’m like most people that gave tried the stingray, it smears windows and looks awful. I will say I like it for indoor work on lightly soiled windows that are not tinted. I have a coffee shop job and it cuts through the syrup that splashed on the window. I hope Unger reformulates their solution ASAP.
I should have mentioned that i would be using it on biweekly accounts, light soil. But good feedback, thanks guys.
I’ve only played around with mine a bit but I quickly noticed that what they recommend for a wet pad is too wet (the solution dries bad). Burn that out on a couple plates then it start working pretty decent, even in direct sunlight.
