About the cal-lab warranty, we not like other ordinary products like have warranty 1yr, 3yrs or 5yrs... we have the unlimited "warranty" (according LLSWA) even u used cal-lab products for 10years, which means after 10years and it spoiled that time, you can do exchange too by bringing the damaged unit and paying Rm25 (for IT pack) to office, the office will exchange immediately on the spot for a working unit for u... but let say if u plug it by today, then tomorrow have very strong lightning strikes the cal-lab products till damaged, but you used for 1day or few hours only, that was not defect product, it is protected your equipment out from lightning strike, so for tat case we have to charge u RM25 to do exchange too even used 1 day... cal-lab products is used to protect your equipment, if cal-lab products failed to protect your equipment and u did the proper installation too, u have the right to do complain...

If you using IT pack, u must ensure all the pc equipment's power source must come from cal-lab, then cal-lab plugged on wall socket... I do a bad assumption here, let say all the equipments plugged on cal-lab, except your PC speaker plugged on wall socket... but the lightning strike the power line, the surge will strike speaker, later on the surge will pass thru speaker from the data cable to system unit... so your system unit will get burnt too even the system unit plugged on cal-lab... hope u can get my meaning...
