## Customer Reviews

### ⭐⭐ Big leak
*by I***D on 3 May 2023*

The bottle had lost 10-15% of its contents during before it arrived and the liquid was not blue anymore. Color was dirty and almost looked like the liquid had reacted allready. Price was cheaper than many other products, but I reccoment spending that little extra for a better quality kit
