This trigger serves its purpose perfectly. It's not perfect, but it creates enough airflow to reduce soldering odor a bit. It also looks well built and the extra filters are a nice touch. I would like to point out that for best results you should try to solder no more than 6" away from the fan if possible. My only complaint about this product, which is why I'm only giving it 4 stars, is that it's a bit noisy.
