It does the job. The coating becomes grey and cloudy, so be aware of that when you spray it on the soles of shoes, door mats, etc...I wish I could use it on my windshield! but then I wouldn't be able to see through it....

I downloaded the free trial app. After uninstalling it, I still got a multiple daily nag screens in my info bar. Finally, I uninstalled the smartdraw tool bar that was sneakily installed in Chrome and the info bar nag screens stopped. Additionally, I unsubscribed from their emails several times with no luck. Still got spammed every day. The only way to stop the emails is mark them spam. Do not download and install this product.

I picked this up a few weeks back so haven't read it completely. Still I think not the best book for anyone experienced with MS Access. There's lots of basics but not a good balance of depth. I recommended taking a read through before you pick it up.

This guide is very flexible which I think warrants additional patience/focus when using. After a few mess ups I'm starting to get the hang of it but every once in a while I won't hold it completely still resulting in uneven lines and forced to shave it all off. Definitely not a product you try for the first time before going out. Give a few tries and see where it takes you.
