Should I get a diagnostic tools with a lifetime warranty?

Every manufacturer offer various warranty terms. Some companies sell diagnostic toolswith a lifetime warranty, while the others only offer one-year or two-year protection. The cheapest models usually do not have any warranties at all. We think that five-year warranty is more than enough for the most diagnostic tools.
