I own all these tools and have found them very useful. I usually research an item prior to purchasing it myself, and I try to purchase items that are multi-functional or an absolute must-have to make my life easier. As an Amazon Associate I earn from qualifying purchases when viewers purchase ANY amazon product after going through any of my suggested items, but not necessarily purchasing the exact item. I'm hoping that this will help subsidize the maintenance of this site in order not to have those annoying advertisements. Thanks for your support!
