I'm a newbie at home manicures and found this pretty straight forward to use. My nails look great and they cured immediately.

Best back razor I have used and I have tried a few. This allows you to use regular blades so replacements are much easier to find and cheaper.

The first review on this product -- where the author indicates that this adapter works with the Samsung 2494 -- monitors is dead wrong. I purchased three of these adapters based on that review (I have three Samsung 2494HM monitors). The adapter is too large to fit in the recessed space on the back of the Samsung monitor. In order for it to fit properly, you'd have to either carve out plastic on the monitor, use a grinder and grind down the corners of the adapter, or get longer screws.

Great book, lots of great information in here for beginner, intermediate, and even some advanced users. I've been building a small db in Access for my work and this thing has been a great reference.
