Pros : As a newbie to stained glass design, I am really trying to get my glass cut to the right size and get the solder looking good. This product does work well, but due to the thin width, a little solder uses up quite a bit of the wick. I have used it very successfully to fill gaps where solder doesn't quite cover.
Cons : It takes a good bit of the wick to remove a relatively small area of solder.
Other Thoughts : Would love to see this in 3/8" in width, or slightly wider. Works great to fill small gaps. Very flexible and disappears within the seam.
