I can't see paying more for something like that when good old insecticidal soap sprays work fine against mites and thrips for sure as I've conquered both using it. I just bought a spare bottle of the Safer's End All concentrate for $14 and that makes 10L of spray. A 1L of the ready to go of the same costs a dollar more. I add 10ml/L of canola or neem oil to the mix and as long as you are diligent about sticking to a schedule and very thorough they are gone in a couple weeks. Every 3rd or 4th day for 4 treatments does the trick for me.
Something that kills the eggs too would be quicker but is generally much more toxic. May be needed if you have a room full of plants tho but for the average home grower with just a few plants the soap sprays work fine.
