I have been a worldstart customer for several years, making fewer than a dozen purchases. Every product received came with a 'surprise' - none of them pleasant:
1. USB to SATA/IDE device DID NOT make a duplicate by pressing the button as advertised; however, it was well worth the price for its other features.
2. SystemMechanic (a real piece of trash) DID NOT install on all my computers as the ad said - it was only good for three computers. It IS NOT for lifetime, but only one year. The specs DO NOT say that internet is required, but it is! (What if the problem you wish to fix is a lousy internet connection?). Customer service HAS NOT responded to numerous polite inquiries.
3. EasyLink DOES NOT automatically run when plugged in to USB port (this is a nifty, but slow file transfer product) and only works part of the time with Windows 7. The software must be executed from the host computer(s). I also found this product for 1/3 the price elsewhere.
Their shipping is slow - often takes 10days-2weeks for them to SHIP the product though they bill your credit card immediately.
My advice (after nearly 40 years of systems integration work)
1. If you see a product you like, go to the manufacturers site for the specs - do not trust the hype of Worldstart.
2. If you decide to purchase, do a bit of searching, you may find it for MUCH LESS elsewhere.
3. If you decide to buy from Worldstart, be prepared to wait an extended period of time for delivery.
DO NOT expect customer service
DO NOT count on tech support.
