Customer Ratings & Reviews

The installation was fairly straight-forward and following the instructions led to a bubble-free finish. It is providing the additional protection I wanted. Only complaint is that it is a finger-print magnet and smudges easily so I am constantly wiping it with a micro-fiber cloth. If I can find another brand that is easy to install and stays clean on the surface through usage, I will replace the Zagg.

4 stars! Has helped protect my screen immensely. No scratches or scuffs.

I needed a screen protector to go with my new phone, purchased this online. I love the fact that it fits so well and was so easy to put on, thanks to the guide that was included. Better than any I've had before.

Zero stars if I could. Don't get fooled like I did. This is not glass. They say it's hybrid glass. But I question that. It appears to be TPU or something similar. You can actual bend this in half. You can't do that with tempered glass. I figured since I bought it as least let me try to install it. Oh, hell no. Lots of air bubbles. Plus I noticed it was peeling up. Not sticking. I wasn't even touching the phone. It was just sitting there. All this money for this? No no. Back it goes. I'm officially done with Zagg. The search continues for a screen protector for my S21

So many of these reviews aren't paying attention to what the product says it is. THIS IS NOT TEMPERED GLASS, NOR DOES IT CLAIM TO BE. This is a hybrid material using D3O, a liquid polymer. It has some of the properties of glass while being more flexible and less prone to shattering. It will not feel exactly like a glass screen, and they don't say it will. There's a slight bit of "grip" to it but it's minimal compared to other film protectors. It's not that hard to install, and the bubbles are easy to remove. I can't speak on the "visionguard" aspect, but I have zero issues with this thing.

Great product. Easy to apply but make sure you pay attention to the instructions.

It has cracked but not my phone screen. And is free to replace.

Be sure to have the GeekSquad apply this to your phone! Product is perfect!

I have had these before, they work great and come with a guarantee to be replaced as long as you own the phone.

Terrible! When you peel off the first layer and place it on the phone, it stays adhered to the protective layers and not the phone! I thought I'd installed it, but it was too late and I threw away the actual protector with the protective layers. Total loss of $40! I've installed these for years and never had a problem like this!

Love this phone. The camera is amazing. Tranferring my info was a breeze. A lot of great features.

Upgrading from a S7 to a S21 was the best decision. I love this phone and all the new features.

I purchased a new S21 today and needed screen protection. I purchased the ZAGG - Invisibleshiel GlassFusion+ 3DO. If you are looking to waste your money then this may be the product for you. I have applied glass protection to numerous phones in the past but have NEVER had such ridiculously pathetic results. I read the instructions, watched a video and attempted the install. Peeling pack the protective sheet separated the product from the carrier sheet and using the included wipe left a significant number of bubbles in lines running the length of the screen. These proved to be impossible to correct. I will be removing this product as soon as I am able to get a product I have used in the past.

Impossible to put on. I have a Galaxy S21 5G and it appears to fit if you can get it on. No instillation video for this model. Now it is trash, hopefully BestBuy will issue a refund.

This is not glass. This film on the screen lasted one week before it had been torn by a pen that went into the same pocket as the phone. The Zagg warranty is not free as they charge for shipping. I can get a better screen protector online for the price that Zagg charges for shipping. Quality is bad. Value is awful and not worth it. Ease of use, complicated for first time users of film.

When Zagg says "Glass" they mean 3rd world cheap thin plastic film. The application is fine except its entirely to easy to have the backing thats held on by static peel off when trying to get the sticky side off.

That Invisible Shield Glass Fusion is no good. If I could I would rate it below poor.
