Built in WiFi sends images to my smart phone. Great for planetary & lunar photography. Lets me monitor my telescopes while inside. Works with my both 1.25” and 1.8” eyepieces. No long exposures or stacking images, so not for deep space or very low light. I’m very satisfied with this purchase!

The headline should say it all. This Eucos is a fantastic design for smart phone use. The remote is exceptionally handy and so far had work flawlessly. The tripod is lightweight, solid and stable. This product is good to go.

I chose this neck mount phone holder with clamp style grip because I don't have a magnetic case and didn't want to also have to purchase a new phone case. Love that you can pivot the clamp to horizontal or vertical. The neck portion is soft around the neck and the piece that sits on the chest isn't uncomfortable.

I've had a number of K&F Concept products and found them pretty good so far, and this one isn't bad, but it has one obvious flaw that caught me off guard. What you get is an extendable grip that can hold your phone or tablet in landscape or portrait mode. There's a screw thread on one end and another on one side, so you can place the clamp on the vertical or horizontal axis, so you can take landscape or portrait photos depending on your needs and almost independent of your tripod. The thread obviously fits standard tripod screws. The good thing about their design is that there's a button on either side. When you press it, you can pull the clamp out and lock it in different positions against a ratchet. That means you can open it wide. Whether you extend it like that or not, you can then keep pulling the clamps against their spring-loaded mechanism that ensures your grip. That means I can put my phone in the case from the beginning to the end and it's one of the biggest flagships on the market. This mechanism works pretty well and is better than similar clamps I've had and will now discard. The whole thing is very lightweight as it's made of plastic. The other end of the screw thread (the end, not the one mounted on the side) is a cold shoe clamp for attaching camera accessories, which in this case would probably be a microphone. What's the downside? They forgot that phones and tablets belong in protective cases and any assumptions about them should be considered from that perspective. I don't want to take my device out of the case to mount it. Unfortunately, since they forgot that, they didn't take it into account when designing the rubberized clamps, which doesn't account for the perfectly normal extra thickness. There was enough room for that, they just didn't do it. Which is silly. It holds my phone in its case, but when it's in landscape mode, I don't think it's good enough to use it long-term. The middle part is also too thick, so it may conflict with the extended camera lift that flagships insist on for no reason. If it were less thick and the clamp ends could handle a larger radius, this would be significantly better. You can probably ignore this if you're not using a case or are using something incredibly thin. But even without my case, my current phone has flat ends instead of rounded ones, so it doesn't fit well in landscape mode. Which is a shame, as it's just not up to their usual design standard and it's a very predictable problem.

The K&F Concept CPL filter for cell phone cameras has convinced me overall.

The filter offers solid workmanship and ensures significantly better photos, especially in difficult lighting conditions and reflections.

The clamp mount is easy to use and holds securely on the phone. I find the magnetic mount of the lens particularly practical, which makes attaching and removing it very convenient.

A small disadvantage is that the filter is sometimes a little difficult to align, and with thicker cell phone cases the clamp mount can be a little wobbly.

Despite this, I am very satisfied with the image quality and handling. A good product that I can recommend to all smartphone photographers!

The K&F Concept universal cell phone camera lens set is perfect. I'm often by streams and especially around midday the shots are always a bit bright.... I've often heard that you can get a lot more out of an ND filter. The clamp holds the filter securely over my P40 Pro, even with a thin case. The filter can be easily adjusted with the clamp. Since you can adjust the filter, you should take the time to experiment a bit. It's worth it! I was able to create much better saturation. It comes in a sturdy, sealable plastic case and can be stored in my gimbal bag. I'm very satisfied. For me as a YouTuber, it's an inexpensive, simple improvement in video quality. Happy to give it 5 stars.

This is a great lens filter for use with the smart phone
It has a nice effect on the photos and would recommend giving it a go and play with the settings available on the phone as well to get a great result
The clip itself is a little large for being portable but it does hold it in place well so it does the job.

I lost my small travel selfie stick on my last trip. I liked that one a lot and it also had a remote. It was very light and sometimes not super sturdy. I decided to get this one which is slightly bigger and maybe a few ounces heavier. I thought it might be too bulky for my purse etc..but it’s great. I feel like it’s sturdier than my old one.

I like how the phone clamps in. At first I didn’t though. I’m used to the spring action kinds, but sometimes my phone with its case would pop out of the spring action clamp because the case usually makes it a tad too big for the clamp to fit really tight.

This clamp is more like a vice where you tighten it manually. I thought it would be a pain but it’s really not. Once you have it opened to the right width, I can even slide my phone (with case) into it top down if I’m feeling lazy :). Otherwise a quick twist of the knob lets you slide it in and tighten.

Last thing I did use it today longer extended and it blew over in the wind. It’s obvious it’s going to happen if it’s top heavy but for every day use it’s awesome!
