Really good product! Looks and feels very good. Sizing was accurate.

Cons: For constructive purposes only (I love the product!)
I would have liked to see more metallic brightness in the sparkles to make it look more like a genuine metallic ring (like tungsten carbide). Its luster was at about 85% of what the photo shows. So, the photo was taken in brighter-than-usual light. I don't fault the product for this, but it's something that could be improved. If this might be an issue for you, go for the lighter-colored options.

I wish I could give it 4.5 stars!

I really liked the results from using this whitening system. I had a noticeable improvement in my teeth for sure. I recommend finding a video of the process to make it easier to understand how to use this.  I also recommend adjusting the amount of time required to keep the tray in, in order to reduce sensitivity. When I left the tray in for the full suggested time, I felt sensitivity throughout the day. Once I reduced that by a few minutes, I was ok. Also I realized this should be done before anything comes into contact with your mouth (eating, brushing, flossing etc...). Otherwise it will sting, burn, leave white patches on gums that do vanish after a short time, yet very uncomfortable. Overall, I recommend this whitening system.

I love this stuff! It makes a huge difference on the visibility of my scalp. It also adds weight and an all over resistance to movement, I'm not saying this is good or bad, as it depends on the situation. There is more product with this brand, than I have been able to find in other brands which is nice. I will definitely be purchasing this again. I would love to see this available in a lighter color, maybe some blonde.
The downside, and reason for four stars is because it does rub off on whatever touches your head. Hands, bushes, combs, clothes, etc. Your hair and scalp will still look fine, but whatever touched you will have product on it visibly. I have been able to counter this somewhat by combining with dry shampoo spray.

Great product!  Simple installation.  I experienced a noticeable  decrease in sound and vibration  after adding the SDS to my TenPoint crossbow.

Great product, noticed a difference as soon as I installed it, took me 45 mins. to install, still waiting long term review but I would recommend this product to everyone.

Had never heard of product before, but reading reviews and especially since this product was about the only one that would actually fit for product, i gave it a shot. WOW!!! This screen protector works great, hardly noticeable. Watching youtube video really helps before applying. Would recommend product. :)

Amazing product. Made a significant difference to my laptop. It reduced the weight and helped it to run cooler and faster. I should have purchased this months ago. A must have if you're interested in improving the performance of your laptop. I would purchase another one, if needed!

The first time I used this product, I felt incredibly sharp throughout the day. I don't notice the effects as strongly as before, but I think it does help.

I have been using this product for my dog for over a year. I could definetly see an improvement in her breath when I first started using it. As time has passed, I hardly notice a difference. Maybe I would feel differently if I stopped using the product for a short period of time. I pour a cap full of the product into 2 cups of water.

It works very well in conjunction the advanced oral care spray. I could visibly tell a reduction in tarter. This was not a replacement for brushing my dog's teeth. I still ended up getting a tarter remover tool, which works wonders in comparison.

Previously I had used tropi-clean fresh breath. This is stuff is better, but not all natural.

On a side note, my last order came damaged. Luckily, I had an empty bottle on hand that I was able to pour the product into. I would not have been able to use the product in the damaged bottle.

It's hard to measure how well a product like this works, unless you only use it on half your face (which I did not do).  However, I feel a tingling sensation when I apply it to my skin, which gives me the feeling it is working.  Also, it does seem like my skin around my eyes (which tends to show age the most) is a little more smooth since I've starting using this product a few weeks ago.  I also use other skin care products and a regime, so I cannot say 100% it's a result of this product, or it isn't something my mind wants to see, so does.  I really like that there is a little pump that seems to dispense just the right amount.  I see from previous reviews it used to just be a squeeze tube that tended to burst, so I am glad I got one of these improved packages.  I'll update if I see any more results, but for now, it seems to be working well.

This product was excellent.  I thought that because of the cost it would not be great quality but I was pleasantly surprised by the huge difference it made. There was a bit of a smell to the item but it quickly faded. I would highly recommend this product.

Bought this item for my Ipad Air recently purchased.  I got the product quickly as promised, and installed it with the step by step instructions from the link provided.  [...]

I've installed various other screens on my other PDA's.  This product is unlike some of the other screen protectors as it requires the spray that comes with the product.

As I usually do, I turned the shower on to knock out the dust in the air, washed my hands and wiped the screen with the lint free cloth provided with the kit.  I then removed the screen from the sheet and sprayed it down on the contact side with the spray bottle provided.  I also gave a couple of sprays directly on the ipad's screen, and then placed the protector as per the instructions.  With the rubber wedge provided, I squeegeed the remaining fluids, and I wiped the excess with a microfiber towel.

After completing the process, I couldn't wait and turned on my Ipad sooner than recommended.  As the product hadn't fully dried, there was a slight rainbow effect.  About an hour after use, the rainbow effect diminished and was completely gone a couple of hours thereafter.  At first there seemed to be some spray residue on the screen, but the next day all residue and rainbow effect were completely gone and it was crystal clear.

I've now used this product for several days, and have noticed that it feels great.  It has a little rubbery give, and makes the screen more scratch resistant than my other harder plastic screens.  I would recommend this product, and at $2, it's an absolutely great value.

Installing was easy enough.  It works good and I do see and feel a difference in my skin.  I'm glad I purchased it and will continue to use it.
