The spy cam is a joke! You will be recognized via USB from any of my computers, not even about new USB 3.0 interface card. The manuals supplied with the mini-CD contains data in cryptic characters that XP can not detect. After retries (also with the new notebook) do not even appear the warning light. Only the clock is also pretty much, the bracelet does not look too bad, but is made for Goliath. In the narrowest setting the clock dangling still on my arm, though I'm not a lightweight at 90 kilos. Conclusion: From purchasing discouraged, except: You want a clock without technology, from which you do not know how long is still running!
