Great, but some things to note
Great product. Make sure to thoroughly cool this while running anywhere near the specified limits (a very high CFM computer fan will help).
The included coil (made of copper tubing) works well for heating, but gets very hot on its own (which it can carry back to the board if you aren't careful). I'd recommend either running distilled water through it (for cheap: bucket + pump; for fancy: reservoir + pump + radiator), or making a better coil using litz wire, which should more efficiently deliver power from this to the object you are trying to heat.
Final note: don't accidentally short the two aluminum heatsinks together (the heater won't work).

I would consider it a good hobby or experimental device though
My thoughts are a bit mixed. What you see is what you get. There is no enclosure and no documentation. This will draw quite a bit of current. Operating with the included coil it ran around 95 kHz and with some 1/2 inch copper tubing in the coil was able to reach temperatures for soft soldering when supplied with 48v dc. I doubt it is designed for that though, and is unlikely to be able to do that repeatedly without lots of fiddling.
I would consider it a good hobby or experimental device though. It will get you into induction heating on the cheap.

Overall it's not a bad purchase.
So when this arrived it wasn't in the most secure of packaging BUT, it worded. There was an insulated diode in the circuit that seemed to wiggle around BUT, it worked. Everything else will th this item went well. Also if you use this DO NOT BRING THE VOLTAGE UP SLOWLY. The circuit won't alternate and you'll over heat the MOSFETS. You'll have to connect It to a switch or pug it into a supply already at its peak voltage. Overall it's not a bad purchase.

Works pretty well though it seems to need a power supply ...
Works pretty well though it seems to need a power supply that needs a very sharp rising edge. If the power supply doesn't have a sharp edge then the device seems to be latching up and seems like it is shorted.
The heater seems to be able to run above the 1KW rating for short periods. I was able to run it at 2KW ish for less than 10 seconds

Absolute junk (revised to seems to work on 3/6/17)
Absolute garbage! Wish I could give 0 stars for this waste of money. Followed suggestions of other raters to bring power supply up first and then connect heater, ran for five seconds and then shorted and will not start again just draws max current from power supply. Never got a chance to try and heat anything. DO NOT WASTE YOUR MONEY ON THIS!!!
Addendum posted on 3/6/17: Against better judgement decided to give this another chance on the possibility I got a lemon the first time and ordered another unit. Second unit seems to work as advertised so far with one proviso. The coil gets crazy hot quickly with 36 volt input. Definitely requires water cooling for the coil and forced air for the capacitors and heat sinks at this power input level. Low cost entry to inductive heating if you are careful with waste heat management.

Works as advertised.

It would have nice to have a manual.
