I have to admit I was a little skeptical of this product before purchasing it but I decided to order it to put me over the "free shipping" cut-off amount.  I have not been disappointed.  The various heads allow you to put the glue where you want it very efficiently.  The dowel hole heads and pinpoint applicator have been great.  Also the roller head is very efficient for large glue-ups as the glue is distributed evenly and results in very minimal squeeze out.  The only thing you have to stay on top of is cleaning the heads as soon as you complete the assembly of your project.  It is not a big deal and nothing more than running them under some warm water for a few minutes.  You're then ready to go for the next project. I keep it in a convenient spot on my workbench and would recommend it, especially if you are looking avoid to paying shipping charges.
