I don’t know how households get by without one of these. It quickly dispenses wide sealing-tape around a box securely and accurately. You can wrap up a package in seconds. We use it many times a week. Mine is at least 15 years old and will probably last another 15. Wide tape is often much better than the ordinary stuff, so we often find ourselves snipping off small bits from the dispenser.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
