Excellent presentation and product. The 100w charger is indeed 100 watt-rated after testing. The iron heats up and cools quickly with the integrated heat sink. You may not know, but it also has a compartment to store solder! I just wish it had a place to store flux paste when traveling. As an extra bonus, you can change quite a few settings from the integrated menu. The screen is oriented such that it’s easy to read while held in the right had. As a lefty this was nearly dealbreaker. However, you can set the display mode for left-handed orientation. Fantastic!

Arrived well packaged/protected. All accessories included are exactly as described. With my 140w pd power supply, i cannot use 100% power or the soldering iron will not start. I had to adjust the power percentage little by little until it didn’t shut down upon starting heat. I am at 74% power setting and the voltage is 20v. The soldering iron will heat up at a decent rate and maintain the heat perfectly. My pd power supply is not a cheap unit, well built. I am surprised i’m unable to run max power on the soldering iron… maybe there could be a firmware update to fix this weird issue. Otherwise the unit is nice, and a welcome upgrade to my ts-100 from 2013.

As soon as i opened the box i knew this was a quality product. Three materials used are premium and the display is beautiful. If you are looking for a low profile iron you can not go wrong with this one. I cannot wait to get to work with it. Shipping container was great and delivery only took about a week. No doubt i will be showing this off to my friends and buying more.

I am super happy with the purchase. Super fast delivery and a very attentive seller. As for the product, it is of unparalleled quality and beauty – a true gem!
I’ve done a few tests so far. I only noticed that if the device is set to maximum power (100% power), the device turns off, which does not happen at the default setting of 65%. This may indicate that the source is not releasing its maximum power of 100W or there may be some internal issue with it. For now, 80% of everything is OK. More aggressive usage tests will be necessary to confirm this condition. Let’s see.

This thing is amazing. Unlike tips from previous generations of soldering irons, the hs-02 tips have a full heating element+temperature sensor as close to the tip as possible which means it heats up in no time. You’d think that for something so inexpensive they’d cut corners but no way man the soldering iron feels more premium than my $100 hakko. And it has a microcontroller and a screen inside of the iron. It feels so slick and futuristic i just wanna solder all the time now. Unbelievable.
This is my first product from fnirsi and trust me it won’t be the last!
