A digital door lock is simply a fancy name for a pushbutton, combination, or keyless entry lock. With a digital door, you won’t have to risk your keys will be lost, stolen, or copied. There is no AC wiring or batteries, so you won't be locked out during power failures. And you’ll never have to pay a locksmith to change out your locks—you can do this yourself.

Digital door locks are available nowadays with a hacksaw-proof deadbolts for standard doors, sliding doors, cabinets, even outdoor gates & fences like around a pool or play area. You can even get locks with a keypad on both sides or with a spring, so door automatically locks each time door is closed.

Most digital door locks have with easy-to-change codes and some even come with a key override option so that a master key can be used to open lock as well as combination.

#2. Simplicity: Will I be able to navigate web sites and find tools and understand how to properly use product or service?

#3. Needed products or services. How much competition will there be?

#4. Cost Is business priced at an affordable range for all income levels? Is fee hidden at end of a long sales letter or do I have to fill out a form to get to price.

#1 I have answered interesting ads to find web sites that have no information at all about people or company behind product. For all I know it could be a whiz kid with a computer in his bedroom reselling someone else's products. Anyone can take a professional course on writing sales letters and learn what psychology triggers responses in people’ behaviors. I haven't seen an insurance policy yet for networking programs. Without a credible person or company behind product or service, at best you are gambling. Why spend your time and effort and money to gamble on an unproved company even if it is free?

What are you chances? 50/50 if company survives. 0/0 if they don't. What's your time worth?

#2 Many times in studying web sites I come to I take into consideration how long it takes to load. I look for choices available to reader.

I do not like flash presentations and should have choice to continue viewing site without them. Most professionals using flash have an option button to skip flash. It is a proven fact that college graduates and older do not go for flashy presentations. They prefer a well written attention grabbing script.
