I was very impressed with this Reflow Oven. I had read and seen YouTube videos which were more than a bit negative. They provided information as to how to eliminate the smell, how to improve performance, etc. etc. But I just plugged it in and ran a couple of dry runs and observed that it did not smell anymore than a household kitchen oven when first turned on -- not much. I am an electronics engineer and needed an oven like this to build prototype surface mount boards. I loaded my 120mm square (4 3/4 inch) board with SMT parts, crossed my fingers, and ran the standard automated F1 temperature profile. All parts from very small to some large components (mostly1206) came out beautifully soldered. I am so glad I didn't listen to the OLD negativity. This company appears to keep improving their product and keeping the price down so that professionals and hobbyists can be successful. Thanks also to the supplier, who delivered the T962 on time when I was needing to quickly replace my hot air gun.
