A good quality "square" filter system for photography. One thing to note if you are considering this system, the adapter ring kit does NOT come with a 55mm ring at this point. I raised the issue with K&F through their Facebook page and a response to that said the point would be shared with the appropriate people. Who knows, maybe it will come with a 55mm ring soon. If you need such an adapter for one of your lenses, you have to buy it separately. That means it's well made and sturdy enough to last for years I think and apart from 55mm there's a fair choice of adapter rings in the kit, eh

The system is very well built and they sell frames to take advantage of other square filters you have from before.
It comes very well presented, in a case.

Unfortunately, the original box of the product comes with the Amazon label directly attached to it, and opened.
Very bad on the part of Amazon, which sometimes sends cardboard to wallpaper the house with an SD card, and in this case it is worth keeping the original box, they send it unwrapped

Among several domestic and foreign companies offering square filters, I decided on this one because it is easy to put on and take off from the lens, it is thin in the front and back, and it comes with a C-PL filter
For C-PL filters, just open the lid and drop in from above. If you make a mistake in front and back, it will not fit.
The square filter has just the right amount of friction and doesn't feel like it's going to fall off.
Almost all metal, except for the four metal adapter rings and C-PL filter, the holder alone weighs 110g.
In terms of design, the overall impression is sophisticated.

My seven year old granddaughter loves her metal detector and has had hours of fun.

Great metal detector!

I have never tried this hobby before, I got this Metal detector a couple of days ago. The device itself is quick and easy to set up with no tools required, its lightweight and comfortable so good for long periods of use. It also seems to have all the features you would need. I have only tested it in the garden so far as it has not stopped raining, it finds the nails and £1 I hid easily, the pinpoint mode works really well.

Although I had it up running and working in a few minutes it will probably take a bit of time and practise to dial all the settings and preferences in too experience the full functionality of this detector.

The metal detector compacts down to about 1m and fits into a carry bag that is included for easy transport.

I would say the metal detector is great for beginners who do not want to spend a lot of money before they know if they like the hobby, I am sure you will make some great finds with this machine.
