Happy With It
For the money, you can't ask for more. Easy to use, takes very fast readings. If you don't need laboratory accuracy, this will do the trick.

Still a Great Speaker.
I had the Z4i for a long time and sold it when I moved 3 years ago. Since then I have tried various PC speakers, including the Harman Kardon Onyx Studio 5. None of them could hold a candle to the Z4i. Fads come and go, but good design prevails. If you find a used one in excellent condition, go for it.

Fast charging.
It does what it is supposed to do: charge fast. I am using it to charge, among other things, my Samsung Galaxy S6 Edge and it charges it just a tad slower than the factory cable which is quite fast. Seems to be well made, flexible and takes bends easily.
