This product is amazing. I am using it for over a month. It works exactly as it advertised. Very light in weight and silent operation. It has multiple input and output connections that are handy. I tested the over voltage , under voltage protection, works great. When the battery voltage goes below 11 the circuit automatically cuts off the load to protect the batteries. Overall very professional looking product.

A little downside is , if you are in US and buy from Vitor, shipping from Portugal takes time. But dont worry, Vitor is a genuine businessman, he always retained good communication with me when I asked for the update on the shipping delays.

I was so happy with his honesty and communication that, I bought more cool gadget from his shop and will continue to buy.

Although I do not have a testing bed, initial deployment produced coherent values and accurate changes. The casing is solid and the probe part robust. Deployment is as simple as it gets. Support was also wonderful. My questions were answered very quickly and thoroughly. The shipment also arrived only a few days after ordering.

This is much smaller than most of the other reflow controllers. I am a huge fan of the rocketscream offerings but needed a smaller portable for a small attic workspace. The software is simple, which translates to simple to use. Don't expect huge customizations, the software works, to get you a proper ramp up and down. The hardware works well. I did not push my luck to see what the maximum amp or duration the hardware would support, but it does the job.
The manual is complete, but you still need to understand what is going on during a soak cycle. Recommend this w/o hesitation for those starting out, especially considering how little it costs.

Nice product, but size (98 mm x 75 mm x 4 mm) is bigger than I expected (no information about size is available on line). Package is ok. I strongly recommend it.

Product never shipped, however I see they are still selling this item. I suspect this is a fraudulent seller, buyer beware.
