100% Blackout Blind, 145 X 250CM Portable Blackout Blind with 30X Nano Tape,Stick on Blackout Blinds for Windows Fits Any Size Shape, Temporary Blackout Curtains for Bedroom Nursery Loft Travel RV Car

Works very well on upvc window frames. The sheet can be cut to size using the proved cutter or scissors though I have not cut mine. Attaches to window frame using double sided sticky pads. These are reusable to an extent (stay stuck to frame, and sheet can be removed and replaced several times. Plenty of stickers are included. I think suction cups would be easier but these work well for occasional use.

Recommend. Good light isolation. Not too difficult to use. Improved my sleep.

It does a great job definitely keeps the light out the room is black ⚫️ dark

The transparent adhesives work great to hold up the 145cm x 250cm blind material on my very large skylight (almost the size of the blackout blind). I used 4 of the adhesives. They are sticky on both sides and hold the blind securely in place (i.e. four is sufficient to support the full weight of the blind). I was able to remove the blind and reattach it without any issues. However, my concern is that the adhesive may lose its stickiness over time due to dust and other debris getting attached to it. Of course, they've provided quite a few of these adhesives so they can be replaced, but you may need to get more once these run out. I stuck the adhesive to the glass directly and it is great that they are clear so they appear almost invisible on the glass. The blind material itself is great, with a black backing and a silver window facing side to reflect heat. My living room is much cooler now after blocking out the sun and heat coming in from the skylight.Pros:- Super strong adhesive but blind removable and re-attachable without impacting strength of adhesion- Excellent quality blind material with silver reflective side- Good supply of adhesives and a blind cutter- Carry pouch for travelCons:- Yet to be confirmed, but I'm concerned that the adhesive may lose its stickiness over time and that I'll need to purchase more adhesive tape once the ones supplied run out.

Ordered this morning and arrived this evening. Our house has a south facing rear with the bathroom window on the east side. It is hot from first thing then the hot air is trapped. We bought this to try to block out the sun and keep the bathroom cooler during the current heatwave. So much material, enough for 3 windows of the size we needed. Plenty of tape and velcro and super easy to install.Simply, measure, cut, attach to the tiles.

Unfortunately, the glue is not strong enough to hold up the material. The sun melter the glue so the cover came off the windows. Useless.

As a blackout it works well, but I followed the instructions and cut it according to the glass size. Now there are narrow openings letting the light it. It would have been better if the instructions have said to allow for a few mm more to void that. In addition, it comes with velcro or sticky pads. With the heat, the glue of the velcro have melted and the velcro strips have moved down the window, and it's taking a lot of effort to fix the mess. The sticky pads are not so sticky when taking the blackout off the window to let the light come in during the day.

Amazing quality, easy to measure and cut. keeps the heat in and room completely dark. It's a must buy.
