Simple and it works without scratching the vinyl. Only problem is that it did not fit into some very narrow areas, but it did the job. Also a bit over priced for what it is.

This is a simple but great product. We don't have any more problems with our car scraping the underside. Although heavy, the unit does slide a little since we live on a slight hill other than that, it's great.

Simple and effective design does the job it was intended to do.  It slips easily over the door and I haven't had any issues with doors not closing after putting the hanger on top of it.  It is not super heavy-duty metal but it appears to be more than enough for hanging jackets or hats or bags over it.

The design screams country with the dainty design but it looks fine in my home office and would work in most areas that were not ultra-modern.

Overall this is simple and functional and does exactly what it is supposed to do.  Recommended.

Simple, basic, works well.  One issue was that the glass surface inside of the screen was dirty, but since the screen cannot be raised it was very difficult to clean. I had to squeeze in a rag using a stick and move around as best I could. Ultimately, surface not completely smudge free. Window can raise to two positions.

It is simple and works good.  I like the option of either a stand or magnet for mounting.

It is a simple product, and works as described. Only fault I have with this tempered glass protection, is that it is relatively easy to scratch - better this than the screen behind, admittedly.

In the past, I have used the plastic self healing protectors. They have a different feel, but show fewer finger marks and heal scratches like the ones I have on this over a couple of days. I think 6 months from a screen protector is reasonable, so pick your evil.

For what it is worth, I shall be replacing this scratched screen with another just like it.

Update, the New protector lasted a year until a drop caused spider cracks. Did it's job, was not scratched in the interim, replaced it again and upping to give stars...

No special technique and it does its purpose. I like it!

Simple but works. I had no problem with having the gel pad stick to my dash as others had indicated. My dash is not leather.

3M makes a great vinyl. I've done a lot of work with cheaper vinyl brands that were stiff, difficult to work with an very unforgiving. This vinyl is the opposite of that. Assuming you prepare the surface properly, this vinyl is super easy to manipulate, reposition and lay. The air channels in the backing eliminates nearly all bubbles for you. Bear in mind that the vinyl is still very thin, and will not hide imperfections on the car's surface, so prep correctly.

This transfer tape works perfectly.
My vinyl sticks great and released easily.
I really like this product over the plastic style transfer tape.
I think it is a lot easier to work with.
It is the consistancy of a thin masking tape.
I have been able to reuse the same piece several times, which is nice.
You can see your vinyl project through the tape for easy placement.
Overall I am very happy with this product and will purchase again when I need more.

Simple and works well. There is no soft material between the case and the back of the iPad but I used this same style case from Khomo for my original iPad Mini and never had an issue with scratching or anything.

It works and does just what it is supposed to do.  If you have a big collection of vinyl and want to hear it, or dub it through your computer. This, and a conventlional turntable, is all you need.

Does the job it is supposed to do. Software for digitizing is basic and works easily, but does not take track identification to iTunes. It needs to be retyped in iTunes

Cleans well enough, just be careful because it does have kinda sharp edges that can damage your vinyl if used at the wrong angle! :(

Simple and easy. Not much more to say about this product.
