These are NOT the $60 slap-on sunshades being advertised online. You need to rub them with something to create static electricity and then they hold nicely wherever you place them. The support from the company is great, as well. I initially thought these worked like the slap-ons, but once it was explained to me how to get them to stick, just rub them with some wool or nylon, it takes all of 10 seconds to put them up. Mine have been in place for over a week with no sign of bubbles or release. I purchased two and cut one in half for the left & right sides of my windshield and left the second one whole to use on the port or starboard door windows when the sun is shining there. Great product, fair price, wonderful company!

Doesnt stick very well.

Adhere doggedly if you rub them on your shirt and build up static. Invaluable on long XC flights.

They work great when you can get them to adhere to the windows. Suggest rubbing both sides on your pants leg before attaching them. It will create just enough heat and friction. I also need a double layer to completely block the sun. Order extra. The smaller sizes attach a little easier.

These work great. Easy to stick and move. The trick is static electricity. Rub on your shirt, pants, or head. They’ll stick to the plexi.

A bit difficult to get them to stick

They work good but need to rub them to get them to stick.

Applied easily enough. A few bubbles hard to remove, but otherwise seems to work well. Seems to stick fine, even on a bubble canopy.

Works great as I have a big bubble I fly in. I slap it where I need it to block Sun or reflection from Sun. If it does not stick just rub on cloths or something to create static again. I now have two, one for pilot and one for wife..

Got a pair for Christmas. They dont stick well - def not slapping them on. I tried rubbing on my hair or pants, etc. Still takes work to get them to stick. Ill give them some more time, but Rosen visors are getting installed this month anyway, but would be good to have on long XC in case the Rosens dont block where needed.

used to restrict sun entering overhead skylight. filtering is satisfactory, but installation was difficult. even using vinyl applicator it is impossible to remove many small bubbles.

Worthless on my RV. You can slap them on, smooth them on, hold them against the plexiglass and say a prayer - nothing will matter. They fall off like the useless plastic rags they are. For almost $10 plus shipping, it’s a total loss and a waste of time.
