Sandeep, I am impressed with the above pictures. Is that a cordless soldering iron?
On another note: I no longer trust HP. I had loved HP equipment from my first HP-67 calculator in college, and even before in high school when they sold some of the first LEDs from the back pages of Scientific American.
I had TWO hard drives begin to fail in a RAID 5 array in my HP server, and their tech support was so incompetent that I ended up actually suffering needless data loss. Only one impotent regional manager has apologized without compensation and with heavy sales pressure for worthless service contracts that even he acknowledges would not have prevented my server problems. I have increased my backup plans and hope to replace the server when I can afford.
Take home message:
DO NOT BUY HP!
