I received mine on Friday, from Amazon. For the money, it's a bargain and very cool, although really not comparable to high quality custom builds in terms of materials, construction, or electronics.
All plastic and acrylic; no major metal components. Manufacture quality looks good; there are traces of scuffing on the clear acrylic cylinder (which could be clearer, as well), but other than that, I don't see any blemishes. Blue and orange illumination controlled by a concealed thumb switch on the handle. (The orange is a bit yellower than I'd prefer, although not as much as in these pics which I white-balanced pretty heavily.) Different (loud) firing sounds for blue and orange portals. Emitter detail is not nearly as complex as it might be, and it's constantly illuminated; no brighter flash with trigger pull.
All in all, quite happy with the piece, for a commercial item, at this price point.
I'm also glad I've got a custom one in the works as well, though!
