Good starter
Used to revive battery works great

Typical product, does what it says, terrible instructions
There is not much to distinguish this from the dozens of other inexpensive Chinese made power supplies, although as I read, this company is based in Hong Kong and as such I would have expected a better English instruction manual. I had to piece together how to use it from the manual and youtube video. Despite having a 2 decimal readout, without a fine control it's hard to get a precise setting. If you need fine control you'll need that. But I did not find one with a fine readout and the voltage and Amp capacity of this one.FYI to people who buy this. To set the current limit (constant current)set all dials to 0.Turn current dial a slight turn until Voltage LED lightsDial up according to the instructions about 3 VSet the Current dial back to 0Short (connect) the leads together.Turn Current dial your desired value.Disconnect the short.The current is now set at selected value even if you cycle on/off as long as the dial is not reset.Short (connect together) the leads

Very capable charging device.
Excellent value to cost ratio. Saved me money by reviving a battery the supplied charger said was defective

Works but with a caveat
Needed a higher voltage supply. Most cap out at 30V, 10A. This one went to 60V, 5A but for some reason, once I loaded it past ~2A, it started messing with my Ground Fault Circuit Interrupt (GFCI) in my wall utility outlet. I could take my 30V, 10A supply (same manufacturer) to full load with no issues so this one has been demoted to running a 12V fan and I found another 60V supply. If you only need higher voltage (a very relative term in this case) with light current demands, this will work; if you need more power, look for a different supply.

Cheap, Accurate Bench Power
For under $100, I have no complaints. Though the caps give off a bit of odor during their first few hours under load, this goes away after a week or so. Have my unit charging an ebike at 60v at 5a without issue. Way faster and cheaper than using a power brick.

A good value
As soon as I got mine, I put on a couple amp load and ran it for a day. it didn't have any drift, and was able to maintain constantly.

Seems to be really accurate when it work
Did give five stars but maybe a week later it spark and now the voltage won't work so useless now.

CHEAP
The voltage adjustment knob was a little glitchy at first but is ok after several rotations back and forth.
