Works as expected and we'll packed No English manual

Overall looks good. The manual is only in Chinese. Will search online for English. Fairly easy to understand without the manual if you know a little bit about electronics. The push button/dial knob for adjustment (rotary encoder) is a bit "flimsy" don't know how long that will last. When you push it to input the values for discharge it is "muddy"... not a firm and definitive click. The button also "wiggles" a bit. When I used it the first time the fan did not come on, causing the unit to heat very rapidly. By prodding the fan with an small instrument the fan came loose and started turning. On the second start up the fan again did not start automatically, however since then it has been working without a problem. The fan self test on startup, then stops, and only start again when heat is high. Check that your fan starts when starting the unit. On the inside every thing looks good and neat like it should. Overall it;s good, will consider buying more to test more batteries at same time.
