I’m generally very happy with my Koi products. The only problem I have had is my spray bottle - the weight on the end of the tube keep on falling off . I sent a message and received a message to say take a pic and send it back, I didn’t have the bottle anymore to take a pic, the thing is this happened about before so I was pretty peeved. I have a new one and so far so good, I felt like I wasn’t believed and had to send photo proof. I think the weight stretches the tube sometimes.
Cheers Suzy 😀
