BLU Products is leaving no niche uncovered, it seems. Just a week after the Quattro line surfaced, we're seeing two more budget smartphones arrive that fill in what few gaps are left. The Tank 4.5 seen above is a rare rugged entry for BLU that's dust- and water-resistant, yet still reasonably slim for a toughened phone at 0.38 inches -- it's the 4.5-inch qHD screen, dual-core 1GHz processor, 5-megapixel camera and 4GB of expandable storage that keep the price in check. The Studio 5.3 II (below), meanwhile, is a direct sequel to last year's Studio that takes on the improved processor and resolution of the Tank 4.5 while throwing in a better 8-megapixel camera. Regardless of the phone, you'll find Jelly Bean and roaming-friendly dual SIM slots with unlocked HSPA 3G. Both are shipping now to the US for $199, which could be just low enough to catch travelers who want a simple smartphone for that late winter vacation.
