Things I love about this machine: The ample length of the gooseneck so you can position it very conveniently, the three speeds of the suction (low medium and high), the light weight, the wheels. What I don't like: the flashing red light that you see out of the corner of your eye in your studio. Easy fix, I turned it around so that the button was faced away, but it's also the on/off button, so, I have to reach around to turn it on. A slight inconvenience, but not a deal breaker. Would have been better as a solid light instead of flashing. I also think that the funnel should be made of metal. It's rubber, so, you can't get it very close to your solder station or you can melt it. You likely don't need to have this right up on your bricks, but I would like to get it as close as possible without worrying that I'm going to melt it. I *think* it's working??? But, fumes are invisible, so, who really knows. It definitely suctions, as I waved a paper towel in front of it and it pulled it in immediately.
