雷瓦早期一直比较低调，其母公司BEST WAY & TRADING CO.，LTD.于2000年就开始销售理发用具，2012年后才正式进入中国市场，该公司研发中心合作方为意大利的沙龙美发品牌DIKSON，其产品均通过3C、UKAS认证，同时多次获得含金量较高的“韩国好设计奖”和“中国红星奖”。
 
The biggest feature of the Rewa nose hair trimmer is that it is cheap, and the two models of RA-555B and RA-555A on sale can be won for less than 50 yuan. The appearance of the two products is basically the same, the difference is that they use dry battery and lithium battery power supply respectively, the lithium battery-powered RA-555A needs to be used with the charger, the degree of portability is not as good as the dry battery, it is more suitable for home use, business travelers recommend choosing the dry battery-powered RA-555B. RA-555B and RA-555A have a very rounded shape and no gaps in one piece, but the battery compartment of RA-555B does not have a sealing ring, so it cannot be washed.
 
Due to the plastic case, the Leva nose hair trimmer is not as quiet as many rubber-based models, and the noise reduction performance is average, similar to the noise level of a handheld fan, which is already quite good at this price point, and is suitable for consumers with lower budgets.
