I’m using these indoors as satellite / rear speakers in a 5.1 setup - the front left/right are also Moukey, bigger shelf sitting models. In this use case they are an excellent upgrade from my prior Sony speakers. With multiple drivers and lower impedance, they create a powerful but clear sound. They were easy to mount (I was able to use the existing universal mounts I had used to wall mount the Sony speakers) - the wiring is all the same as typical speakers - red and black speaker wire, the higher quality the better.They do have multiple mounting options - they come with a swing bracket attached that can easily be used - because I have the universal mounts already tied into studs, I didn’t end up using them - if you remove them, you can access a typical “keyhole” type mounting system integrated into the back of each speaker which is what I’m using.Because I’m using these indoors, I can’t really comment on the waterproof capabilities (or lack thereof) but they do seem to be at least as well weatherproofed as the outdoor speakers that I currently use so I think they’d hold up just fine as long as you can protect the wiring connections from getting wet.Overall, nice speakers and a decent value at the current price - definitely give these a look if you’re in the market for new speakers!

these k&F adaptors, at least for the sony nex, are fabulous. significantly better than the others in their price range. easily equal to the more expensive products that sell for 3-4 times more.

It comes with all types of adaptors also 2 batteries

Can't believe I got this for.99 cent!! It works perfectly and I love interacting with my Alexa!

I do not use these for the UV filter but as a good quality, low cost lens protector. That said:My 1st Tiffen was a 55mm UV Protector I got for the kit lens that came with a Sony a7ii; an FE 28-70. I was so happy with the purchase that I have since purchased three additional Tiffen UV Protection Filters. One is on a Sony E 55-210 I bought used and one is on a Samyang 35mm I bought new. The one I am writing this review for I assume is still on the Sony FE 50mm I bought new but returned and forgot to remove the filter.The point? I treat my lenses, new or used, like I treat a cell phone. That being the phone stays in the box until I have a protective case for them and lenses stay in the box until I have a protective filter to pair them with. And the one I forgot to remove from the returned lens? That is how confident in the Tiffen filters I am. Once I put one on a lens, I never need to think about it again.I have used several brands in several sizes ranging from the cheaper Altura and Polaroid to the mid range Hoya and B & W.Where does Tiffen fit? Well they are no Hoya or B & W but I am no professional photographer. I am an amateur who mostly enjoys street photography when I travel and for my money Tiffen is the best. Yes, you can spend more and get better glass and if you really have reason to worry about ghosting you should look for a higher end lens. That isn't me saying ghosting has been a problem for me. I normally use a lens hood and I think that helps cut down on light reflection. I have noticed some minor issues with it on some shots I have taken in direct bright light conditions but not enough to justify the higher price.I do not stack filters as I haven't had a need to so I can not give an opinion on that topic. I would assume that the risk of ghosting would increase.The short version is this. The Tiffen UV Protection Filter is well made with good quality glass and a metal ring with threading I do not worry will cross thread or strip. They do what I need by protecting my lens. If I was buying a ND or polarizers I might buy a more costly brand but for everyday protection, Tiffen is all I need and the best for my money.Tiffen say it best in their own product description; A small price to pay to protect your investment.

This is a great accessory kit for any action camera. This comes with a ton of different mounts and adaptors, and the price was great.

Have had my previous ones for.10 years so was afraid to.purchase. these are better than the first

It is light in weight. I use it to protect my Sony lens.
