[Samsung Galaxy Note 9 Accessories] bignazpwns:
Seems like all the "Reviews" are nothing more then install video's of people saying oh its so amazing. But if you dig deeper you will find issues that a proper review would of find easy. So lets review it.

Little about my self. I am and Engineer in the fiber optics industry. I wonk on the absolute faster detectors available. We use UV optical adhesives every day. So needless to say i know a thing or two on this topic.

The concept is great and when done right the best way to attach a screen protector. But this comes at a cost. Cheap out on anything and it will show. So lets look at this.

-Full cover. errrr not really Notch cut for the camera and sensors. Odd because optical adhesive you can go full over and have zero impact on those.

-9H Hardness. "Shakes head" No..Its not. They need to stop claiming this every company. Its not 9H.

-Beveled edges. This is a must. Ask anyone who has one that is not beveled how easy they chip.

-UV curing light is a good design and has plenty of LED's to cure the adhesive. "5w max" Honestly im not seeing those being close to 1w LED's. If people want i'll take apart the light but no heat sinking as far as i can tell. So im guessing 3v 60ma .5w each total max output 3w. And honestly 3w is fine. Its very thin and easy to cure.

Fixture is great and works very well. No complaints on that. Just watch a few videos and read the instructions and you will do fine. The Fixture is well thought out so hats off to engineers who did that.

The ugly. This is where things get bad. This is where you can see the corners that were cut and boy did they cut them.

-Dust removal sticker. Don't use them. Cheap sticker and will leave residue on the screen. Save your self some time and just put them in the trash.

-Cleaning cloth. Not optical quality. Again put it in the trash it will just put stuff on the display. Cheap fabric not a quality optical cleaning cloth.

-Alcohol wipe...Well the directions say that but the wipes included are Ethanol...Please tell me these are not medical grade. If so then they have some additives. Well again trash it and use some 95% or higher Isopropyl alcohol. Make sure no color or sent has been added. You want as pure as you can get.

-Absorption pads. Now i would love to say trash them. But you need them. Make sure you give them a good rub down to remove all the lose fibers on them. And give the long fibers that hang off after a little trim. You do not want one to get under the screen or at the edge.

-Dimples on the underside of the protector. You don't need these. They do nothing but put 4 contact points to your phones display. The adhesive will flow an even coat.

-The worlds cheapest UV adhesive...Guys its bad...Real bad. Give you an idea. In bulk the quality optical adhesive is expensive. Well you get what you pay for or in Whitestone's case you don't get what you do not pay for. I searched and i found the supplier for there adhesive. How cheap is it? Well its $1 per 30ml. Stuff we use is $30 per oz. or 29.9ml. Yup that explains everything. This is why they can give you so much and still keep that price point. But for this you want less but higher quality. Combine that with tubes that are not 100% air tight and you are begging for problems. Also keep in mine UV Adhesive's have a shelf life and exposure to oxygen age them faster.

Lots of people complain about the delamination. This is from bad UV adhesive. Keep in mind you have a bare glass surface you are attaching to a glass surface with an oleophobic coating. This coating does after the adhesion of the adhesive. So you really need the proper quality adhesive. The adhesive they use never fully cures. If you check out my video in the Deamination topic you can see even after curing then putting 200w of UV on it for an addition 20sec with a proper industrial UV curing station it never fully cures. Multiple kits i have tested they all do this. But its $1 per 30ml so what do you expect.

You will see pictures of the optical property's of the adhesive. It is my opinion that it is not optical grade. Also you will see a picture of the delamination.

Overall this is a 4-10. Held back by the extremely low quality UV adhesive. The most important part is the cheapest. This is why they cut the notch in the protector. Because it would affect the caners where a proper optical adhesive would have zero affect. I'm disappointed. This was hyped so much but no one really looked at it. It's a great concept held back by cut corners. The proper adhesive this would be a 8-10. This method with the proper optical grade adhesive could do a true full cover screen protector then it would be a 10/10. But i do not recommend this. Price is to high for the corners that were cut. The adhesive issue really needs to be addressed because i would take a few other protectors over this.

Message to Whitestone.

I tested Adhesives from 3 kits. Results were all the same. All the kits were ordered at different times as 2 were from Amazon and one was direct from you. I have identified this adhesive not long ago and this is typical for it. However if you want to play we only use the highest quality materials card then you can go ahead and send me a tube of it. It can be in the manufacturers tube or the tubes that come in the kits. I do not want another kit im only interested in testing this adhesive and i will give you one chance to test some prior and send it to me. I will then report my finding's on here and make a note of it here. If you would like to work together on finding a cost effective quality optical adhesive i have contacts with not only the distributes for these but also with the companies that make the highest quality optical grade UV adhesives in the industry. I do not want nothing in return i will work with you for free to fix this product so that future phones can benefit from it and i have the option to easily order a quality kit. I want a 100% coverage protector and working together this can be done. There is potential here and it is with the system developed for the install and that is what makes the product stand out. My work has a building in SoCal. I go out there a few times a year and i am more then willing to come visit your office why i am out there and we can talk.

Now i know i will get the "Mines perfect best ever" post. But those post mean nothing. You have not tested the adhesive. I have. You just have not had any issues with it yet and you may never have them. But i went ahead and i tested this. Same results every time and i know what adhesive they use now.
