The low smoke feature is just for name sake. Instead it consists of chemicals that causes eye irritation. Though it gets you rid of the mosquitoes but at the same time the smoke it produces is unbearable by your eyes. It acts faster but after some time you will see mosquitoes flying in your room.
My experience using this product was worse, once the coil gets burned out the mosquitoes again started to appear even though the windows of my room were closed and other thing how it irritated my eyes made me stop using it. Now I am using the liquid from good knight that one is slower acting but has good results. So better you also switch to liquid one.
