### ⭐⭐⭐⭐⭐ Review
*by L***N on 27 June 2025*

I live in the south where the summers can be fairly human I noticed a lot of small anomalies on my first layer especially in the summer but they really didn't fear much with the print. This it was small and compact so I thought I'd give it a try. I took one of my Older filament reels and ran it for 6 hours. The next day I used it to produce a print and the first thing I noticed was my first layer was great. So the dryer seems to be working well. I'm great I was going to downgrade it for lack of instructions as there really are none. It has two buttons and no iron off switch. When you plug it in nothing happens until you push a button. The left button seems to change the mode to change the temperature and the time and then both buttons allow you to increase Or decrease. Then hold the left button again to change temperature time. After playing with it for about 10 minutes I was able to figure out what the buttons do and how they worked but it wouldn't be nice if they put some instructions in the manual actually there is no manual but there is a chart for a temperature and time for different types of filaments. I did see a difference after he eating a spool compared to using a spool that I just would zip up in a zip lock bag so I am satisfied with the product. I have been This dryer for a couple of weeks now and I found that by connecting it to my printer when I'm printing and hitting the filament Before it enters the printing There is a significant improvement to the print. I'm using PLA and I only heated to 40 degrees Celsius as it prints And I let it warm up for at least 1/2 an hour before printing.
