The eclectic-looking Rex almost seems like a toy at first glance, but TechCrunch says the feel "suggests tremendous durability" with no "errant rattling." As a speaker intended to be used outdoors, the Rex comes with IP53 certification, meaning it's water resistant and can survive most weather conditions.
How does it handle audio? Well, according to TheNextWeb, it "sounds good" and is easily "on par with the Jambox." Its smaller stature does mean a smaller sound, though, with Digital Trends finding it "predictably tinny" and having "almost no body." This shouldn't be a surprise -- after all, it's only 3 x 3 inches big. If you need crystal clear audio and fidelity look elsewhere. But if you just want a speaker that can go anywhere and take whatever you dish out, the $60 Boombot Rex isn't a bad deal.
