Seems to sum up their entire business plan-- Value and low cost
Conclusion from CNET
Though the unlocked Verykool Black Pearl doesn't have the latest top-notch specs, at $229.99 unlocked and off-contract, it's a great value. Its admirable screen, sturdy design, dual-SIM capabilities, and unique software features make it worth a look if you're in the market for a budget handset.
If you're willing to go on-contract, there are many affordable options. But for those seeking an unlocked phone, the Black Pearl is one of the least expensive options available. For instance, one of our top unlocked smartphone picks , the HTC One Google Play Edition , costs $549. Likewise, the highly rated unlocked Sony Xperia Z has an MSRP of $549.99.
The only unlocked handset that comes close to the Black Pearl's price tag is the Nexus 5, the most notable unlocked phone of late. It costs $349, or $120 more than the Black Pearl. If you can afford that, I recommend you buy the Nexus 5, because it's full of top-of-the-line specs and is running the latest version of Android. If you can't swing the extra cost, the Black Pearl is a compelling alternative.
