Rongcheng was founded in 2013, a brand of Sichuan Juyouge Trading Co., Ltd. Although Rongcheng is an emerging brand, its high sales volume and functional advantages should not be underestimated, which is reflected in the clearer LCD display, larger and easier to operate buttons, and also supports rechargeable and dry batteries at the same time, which is prepared for problems and has a very intimate performance design. The price is moderate and the comprehensive cost performance is high.
