### 5/5 — Tool4seller…où Tool5stars ?

*2024-10-02*

Oui c’est vrai le titre est peut être présomptueux, mais franchement c’est une belle surprise ! 
Plus rapide qu’amazon pour déclaré ces ventes, facile à lire, et intuitif…et encore je n’utilise pas toutes les fonctions mais pour moi, il est largement au dessus de la concurrence ! À tester, vous ne regretterez pas ! 👍🏼

### 4/5 — 性价比还可以

*2024-09-19*

整体感觉还可以.性价比高.但是和优麦云相比.更新的时效差些.另外一点就是看不到昨天具体的 SKU 的订单数和销量.只知道总数.出了多少单.售出多少个.具体的 SKU 数据差不到.而且只能看前一天的.没法查找看前两天或是前三天四天的...

### 1/5 — 用了他们软件，亏了好几万

系统出问题了，导致我的产品被0元购了，他们一分不赔。不怕赔死的卖家们你们就用吧。

### 5/5 — 价格
