Very nice and has the ability to track historical low and high, at the same time allows resetting the unit to clear the old stored memory. Other models do not have reset button to clear the past history.

I would give it a 5-star, but there is one not so good feature:  When fully extended, the unit tends to fall down because the leg will give in to the slight pressure.  It is actually more stable if it is placed upside down.  This means that the manufacturer should flip the design of its leg upside down, so that it can stand up in a stable manner.
