mjkzz.com Reviews 

I bought a lens gear from Daniel in May and I was very satisfied with the product so I ordered the zoom gear the following week. I had to wait a month for manufacturing, but when it was internationally shipped it was lost in transit. I've been trying to contact Daniel since June to get another sent or a refund but have been totally ignored. I've never been ghosted by a business, I am beyond belief. I doubt I'll ever see my money again. Do not give him your business.

I was hoping to give a favourable review on the MJKZZ single water drop kit but my experience is anything but good. The kit took 33 days to arrive with no explanation of the delay.
The box contained no documentation at all, no invoice, shipping form, manual or return labels. Having paid £300+ I expected more.
The drop controller was not as advertised, l assumed it to be an upgrade but there were many functions missing, again no explanation. I also suspect the controller to be faulty.
I did email my concerns but after the initial acknowledgement I have heard nothing since. There are other kits out there , some available from Amazon which would be a safer purchase.
I don't seem to have any redress.
Caveat emptor!
