The only book that tells you about the holes in the Microsoft Windows Operating System AND how to close them up so a hacker canÕt get onto your system. There are a lot of books out there that just TALK about problems with the Windows Operating System. But there are very few that will tell you WHERE the holes are, HOW to find them, and WHAT you need to do in order to stop them. Based upon personal experience, as hackers attacked repeatedly, how they were found out and stopped. If there is one book you should buy and read Ð it is this one. Simple, easy to do fixes to the Windows Operating systems from XP to Windows 10. Screen shots on what you should see, where to find it, how to use it. A must have book for anyone buying, using, or planning to buy a Windows computer.

Just OK
Not too impressed. Thickness is good but I don't like the smell and the fibers/lints it leaves on my baby's skin. I like other brands better.

Great water flosser
Color: Pink+purple
Got it for my 10 year old with braces and it works great! She even takes it to sleepovers! It’s so portable and the travel safe design is great. It’s a very reasonable price as well. Would highly recommend

Works great.
Color: Blue+red
I love how easy this children’s dental floss is. My child with ASD is able to use with little to no help. it’s been years trying to get my child with sensory sensitivities to floss or brush teeth without a HUGE STRUGGLE, however this is very gentle and something that makes our oral health care routine smoother. ( if you know, you know!!) It is very similar to the viral “ usmile” adult version water flossers. My only complaint/issue with this is that it collapse pretty easily and sometimes it’s hard to keep in the locked position while flossing teeth. Overall a good product, and recommend.?

Color: Blue+red
A little powerful for my 8 year old at first but after he got the hang of it, he loves using it.
