CamKix Diving Lens Filter Kit compatible with GoPro HERO 4 Black, Silver HERO+ HERO+, HERO and 3+ - fits Standard Waterproof Housing - Enhances Colors for Various Underwater Video

Having used several magenta and red filters from eBay/ China on previous holidays I suddenly found myself needing new filters for my latest last minute trip to Egypt. I stumbled onto these filters, pack of them for the price of a single clip on, yeah why not.No sooner had I ordered them than I got a nice email from the seller with advice on use and possibly needing to use editing software to bring out the best along with instructions on which filter for which conditions.They arrived a few days later, nice packaging / case for the item with each lens in its own pouch too, along with a handy lens cloth. So far so good.I got to Egypt and being lazy and short of pockets , I only used the first red filter for 5-15m on depths up to 25m with great results. In wrecks with my torch on I took the filter out and popped it up my wetsuit wrist seal for safe keeping.This is a nice little set for very little money. I only wish they did it for the GoPro 3 (60m rated ) case as that's my preferred housing, but that is my only critcism.A great package with great customer service. Really happy and highly recommend.The attached pictures were taken at between 10m and 15m with no editing.

Seems to work quite well. did a dive to 26m

Seems a good product, will know when tested on a dive

The lens filters worked great however the actual lens holder doesn't fit snug to the camera, When snorkelling the lens holder kept falling off and when no lens is in the filter you get a black border around the camera (I've attached a picture to help show this) and the holder was pushed back as far as it could physically go.If you're snorkelling just make sure the lens holder is tethered to your float/stick.

Received the item within 2 days and all packaged up suitably. Kit is extremely useable with 5 filter lenses - 3 red for varying depths, a purple for water with algae and a yellow for night diving.Lens cap fits onto my Hero 4 perfectly, not too tight but certainly won't come off in the water which could have been a worry. The kit is in a zip able clear plastic pouch, ideal for keeping things waterproof. Yet to see the image quality but have no doubts it will improve my videography in post editing!

So I'm generally ok with the product - when it works. The packaging is neat and compact, the filter holder easy to attach and secure, and the filters themselves are easy to slot in, and generally hold their position underwater.What you have to watch out for is trapped air bubbles - maybe best to pull the filter out and back in when underwater.As for filter quality, in tropical water, the 20-50ft filter seems to do the job - coral / fish colours are brought out. The 5-20ft filter seems a little superflous - at that depth you've enough sunlight, and at risk of turning your videos red. The yellow filter doesn't seem to be that useful, turning everything yellow on night dives. I've not used the other ones (and may never have any need to).I'm generally ok with my purchase for the cost, but am not 100% sold on the idea as opposed to software editing.

I’ve added some rubbish test shots to show the colour differences. Not what I’d hoped for or expected! May be better at depth.. this was a quick test whilst swimming in the sea to determine if I should use them the following day on a dive. I opted not to!

The filters themselves are brilliant and work really well, but the clip that holds them is awful very flimsy and doesn't clip onto the gopro session well and tends to fall off very easily, worried that if I take it into the sea or a pool it won't stay on or will easily get lost, now looking to buy another version of the same product.
