Great Stuff
It works well and lasts.  I have purchased maybe 10 tubes of this over the last few years and have recommended it to 2 other people who use it regularly.  When you think the tube us empty, don't through it away, here is what I do.  Cut the seam off at the bottom and using a long spoon, scoop the contents into a container such as a small jar or  pill container.  You will be surprised at how much is left in the "empty tube".  This product is a little expensive but you use only a small amount at a time, plus by scooping out the contents as I described, you get all the product you pay for.  I highly recommend this.
