I've been a GIK customer for over a decade and have spent a lot of money on their gear. I've made at least four trips to the Atlanta warehouse in person, and just took delivery on 16 traps this past week. I just say this as a preface, to point out that I obviously love this company and am very satisfied with their stuff.
That being said...
I recently consulted with one of their reps, who encouraged me to give the GridFusors a go on the back wall. I was wanting to go with two or three of their well diffusors, but apparently their supplier went FUBAR and so further production is on hold. I knew I could just paint these things and use some command strips for a nice temp solution. I had initially just planned to put a bunch of these things on the ceiling.
Anyway, long story short, I had no idea these were just molded styrofoam. At over $50 a panel, this is the first time where I felt as if a GIK product was not up to par. Not only did two of them arrive damaged, but they are clearly very fragile, and a true nightmare to paint. I put three coats on the one in the photo below. It looks acceptable in the photo, but in person it just doesn't look appealing whatsoever.
So even though it may not sound like it, Im not trying to hack on GIK here, just to share my experience and to encourage people to consider only using this product for what it was designed for - a substitute panel in a drop down ceiling. If I would have known these were made of this material, I never would have bought them.
