Master Grip Kit for iPhone 17 Pro, Magnetic Phone Camera Grip Powergrip Kit Built-in 3200mAh Battery - Wireless Charging - Graphene Case for iPhone Cooling - DSLR Style Grip Handle Holder

On October 6, 2025, after using the grip for some time and contacting the vendor who demonstrated how to update the firmware, I’m updating this review to include new insights I’ve gained about the grip. I purchased the grip for my brand-new iPhone 17 Pro Max, which hasn’t arrived yet. However, I’ve been using it with my iPhone 15 Pro Max without the cover that came with the grip. The grip is well-constructed, made of lightweight aluminum, and feels sturdy in my hands. Follow the instructions for pairing and ensure that Zoom is enabled in the iOS accessibility menu. The box also includes a screen protector, which was a pleasant surprise. I haven’t used the case yet, but its lightweight aluminum construction fits very well with the grip. The grip worked seamlessly with my existing MagSafe case. The buttons function well with the iOS Camera app, but when it comes to using them with Blackmagic or Final Cut Camera apps, only the record button, which is the most crucial one, works. Telesin has indicated that a future firmware update may enhance its functionality. To update the firmware, download the free “ReefColor” app by Telesin and ensure that the grip is connected to your device. The system will automatically detect if an upgrade is needed and prompt you to proceed. The ReefColor app is a simple camera app that offers several features, including the ability to re-map the Grip buttons’ functionality. However, its most important feature is the ability to update the firmware if necessary. The Grip’s battery is designed to provide a small battery boost during recording, but it’s not a reliable power source for extended video sessions. For instance, it charged my iPhone 15 Pro Max from 30% to 60% while the phone was off before it completely drained. As per the iPhone battery settings, the battery starts charging in fast mode and then switches to slow mode. For long video sessions, I connect external power directly to the phone using a right-angle charging cable that keeps the cable out of the way when in landscape mode. When I receive my iPhone 17 Pro Max, I’ll be able to record lossless landscape or portrait mode regardless of how I physically hold the phone since it has a square sensor. If you’re looking for a sturdy and well-built grip, this is definitely recommended. I use it to shoot photos and videos for short, occasional sessions. However, when I need to record a long video session, I usually screw it to a tripod and connect an external power source directly to the phone, and I’m all set. The magnets are very strong, and I feel comfortable not dropping the phone, whether I’m holding it or on a tripod.

I’m seriously impressed with the TELESIN Magnetic Master Grip. It says iPhone 17 but I’ve been using it for my iPhone 16 without any issues. It instantly transforms my phone into a DSLR-style camera setup and makes shooting photos and videos feel far more stable and professional. The magnetic attachment is strong and secure, and the grip itself is super comfortable for long shooting sessions. The built-in battery is a huge bonus extending my phone’s battery life, and the wireless charging works smoothly without any hassle. The shutter button placement feels natural, the build quality is solid, and everything just works as advertised. Whether you’re filming content, traveling, or just want better control for photography, this kit is a game changer. Highly recommended for anyone who wants to take their iPhone photography and video to the next level!

I have a iPhone 17 ProMax. I was excited about receiving this product . Much to my dismay the majority of features didn’t work on my phone. Blue tooth worked perfect. Weight was fine .In the instructions many of the buttons said NA. If it worked as marketed it would have been great . But to have only a shutter and a grip without being to adjust any settings ….its a hard no.

This is an absolute value for anyone looking to take their mobile photography or videography to the next level. From the moment I unboxed it, I was impressed by the quality of the materials and thoughtful design. The grip feels solid and comfortable, making it easy to hold for extended periods without any hand fatigue, which is perfect for shooting long videos or photos. I liked boxing too, though it is just throw away. It holds the phone securely in place without any wobbling or slipping, even during fast movements. The built in Powergrip is also a fantastic bonus providing extra battery life when you’re out shooting for hours. Now I have extra power during those long shooting sessions. The ergonomic design of the handle makes it super easy to capture steady shots with one hand, while the magnetic mounting system ensures that everything stays securely in place. Whether you’re using it for casual selfies, vlogging, or professional level content creation, this grip kit enhances the entire experience.

Good MagSafe case, good grip, terrible iOS 26.1 integration. Firmware version according to ReefColor is 6.4. Hopefully, they can fix this with future firmware. Buttons/wheel/toggle unpredictable and fiddly. Sometimes work as configured, often don't. Bluetooth connection is unstable.

I like everything about this Grip…well, everything except the instructions. They appear to be written by Engineers who were too close to the project to do a good job. Sadly, I don't think Marketing would have done any better as they tend to focus on what it can do…not how to use it. They need someone who can explain it to their parents or grandparents. If you returned yours because the zoom didn't work, it's because the instructions don't start off by explaining that you need to download an App for that feature to work; the rest works seamlessly out of the box. If yours stopping working, it's probably because you turned in on wrong (after the initial paring). I had to scroll down to discover this. I wasn't thrilled with having to buy the kit when all I needed was the grip. However, once you figure it all out, it is a well designed tool. It fits the hand well and does what is supposed to. If you are used to having a camera in your hand, the TELESIN Master Grip will feel natural. I would have preferred the shutter on a 45° slope (so I would know by feel that my finger was on the right button), but that's because this is what I'm used to. I also would have preferred an App written specifically for the Master Grip.

I really enjoy my Telesin Magnetic Master Grip Kit for my iPhone 17 Pro Max. It easily attaches magnetically to my existing protective case, and makes it much easier to hold when taking photos or videos. The grip has a place to put your thumb when holding the camera with the grip on, which also help align the grip to your phone. The handle appears to need the supplied adapter case, but I did not plan to use it any way. The controls feel firm and do not feel cheap. All in all the grip is very well made. You use the free ReefColor app to setup some of the grip functions. You are supposed to be able to update the grip firmware via the app but I have not yet had to do that. The grip comes with a tiny user manual that is written in several languages. That is fine, but it is so small as to be almost impossible to read. The website user manual is a web page, and one of the essential instructions (how to turn the grip on) is found later down the web page though the setup instructions earlier on the page assume you know how to turn the grip on and off. It took some searching to find this key piece of information. I wish the user manual that comes in the grip packaging which is well written was available online to download and keep for reference. That would make it possible to refer to those instructions when not on your laptop. It would also make it easier to study the grip's functions. As with any new piece of hardware it has a small learning curve but once you get use to what you see on your iPhone screen and where settings are (the ReefColor app has its own settings on your screen), the easier it becomes to use. I am definitely looking forward to using this, especially for video.

My daughter enjoys creating and sharing short video stories on Instagram. Since she worked very hard last year and ranked among the top ten students in her class, my partner and I decided to buy an iPhone 17 along with this grip as both reward and motivation to keep improving. She learned how to use it within minutes. The grip is comfortable in her hand, the magnetic attachment feels strong and secure, and the built in battery with wireless charging works smoothly. Everything functions as expected and make mobile shooting more controlled and enjoyable.
