I have to agree your layout and organization is MUCH better. Honestly it looks much closer to a professional article this time around. Its easily to follow and well broken up.
Now for my critiques. First and foremost, a thing that stuck out at me the most is that you are woefully short on facts in the specifications area. You say " For it’s price, the Hakko boasts some impressive specs!" but fail to explain to me WHY they are impressive. In fact, you leave out several important specs such as wattage, soldering temperature range, temperature resolution, etc. You instead give me some features in the specs area (they are similar but not the same). Secondly, for reviews of technology equipment, an unboxing style review is often the best. It allows you to REALLY get into the nitty gritty of the device. It can often be a bit difficult to get your head around but
here is a great example of what I mean. It's a review of a computer power supply written by Oklahoma Wolf over at JonnyGuru. I chose this because like soldering irons, computer power supplies are not the most flashy devices. They are much more utilitarian devices. That being said, he is able to write a multipage in-depth details and enjoyable review. If you notice he delves deeply into all aspects of the device from marketing, to craftsmanship, to included accessories, to performance. You don't need to go THAT deep (ie the intricate teardown) but it would behove you to go into more detail than you do now. Lastly, your conclusion section is actually not one. You should never introduce new info. For example, the info about tip choice should have been included in the paragraph about what was in the box. The conclusion section should be all about summarizing the good the bad and the ugly. Once again, see the Okie Wolf review for what I mean.
