Seriously. Plus you can buy these things on AliExpress for 1/5th the cost. And if you don't want to give up your smart phone completely, you can buy slick looking "bluetooth dialers" on AliExpress for even cheaper.
The general cheap small smartphone on aliexpress are MTK chipset phones running android gingerbread (or some other ancient version). You get what you pay for, unless I’m wrong and you actually have some decent products to link.
