anything that is not LGR is dated technology, it simply can't put out that dry of air, with that said, to me it would make a good backup, use it when all other equipment is out, or if you get a job that is so big you need more equipment, those type of dehus are still effective on the initial stages of the job, to knock down the spike in humidity, day 2 and 3 should be left to the LGR's
