I have it for a year, and at the beginning when I put the narrow nozzle and full temperature, the plastic melted, but I managed to fix it because I came up with a solution so as not to throw it away and waste my money. Then I put the larger nozzle and it worked fine. Sometimes when I needed it for detachment and soldering of RF SMD, it saved me. The only negative is that it has the switch at the back, but you get what you pay for, as long as it lasts. Strictly for amateur use.

I also made the mistake of buying it as a second one and it was small, I thought I could carry it to work because I have a zd-939l (which is very good). It doesn't perform at all, while the other one is amazing. Also, suddenly, where I work, it drops the temperature on its own... Tragic. Stay away, guys

Today, 04/04/2019, I bought this device. In the end, you get what you pay for. Spend a few extra bucks instead of wasting them on this product. It has low air flow and when you attach the small nozzle, it barely works. It's like having two phones for the fire department. I'm not exaggerating, it melted the plastic on the handheld tool. As for the main device, the on-off switch is located on the back, so you have to search for it. And it's all plastic, very plastic. Stay away!

Very good for its price range. It seems to have thermal cut-off protection unlike many products in its category. It heats up quickly but unfortunately it doesn't show its actual temperature as it heats up, only the targeted temperature. It has an automatic sleep function when placed on the base, and for safety reasons, it first removes the stored hot air before turning off. Unfortunately, I didn't have time to measure the actual temperature compared to the recommended one, but when used for detachment at 385C, it seemed that even 5C degrees made a difference.
