It also comes with the Sun Rise brand on it. Here's some discussion on
the product http://www.badcaps.net/forum/showthread.php?t=2798

Looking at the scale graduations in your pic it would appear to have
extremely poor resolution for caps in the low ESR range. You really
need a meter with an expanded range reading of say 0 - 10 ohms max.
Any higher reading is meaningless since an electro cap with 10 ohms
esr is useless for anything.
