Las compre por los comentarios tan buenos que tenía y fue una total decepción, no han aguantado ni 1 día en exterior

Soddisfatto del prodotto.

Ne colle pas dit tous lache apres 10 min.

First of all, the negative reviewers clearly didn't read the instructions on the back of the box. You need to clean the surface of what you're mounting onto, as well as the item you're mounting, as to get rid of any dust, water, or oils that will mess with the glue. Then once you've mounted the item, you need to hold it against the wall firmly, if it's a heavy item you should press it hard against the wall for a good 3-4 minutes. I have personally used them to mount a 2kg ethernet switch plus a 1kg 8-plug UK extension lead onto an indoors concrete painted wall. They were still stuck to the wall 4 months later when I had to move. While trying to unmount them, it took me a good 10 minutes involving a strong flat knife (which was bent in the process) to get them back off the wall. The funny part is that the strips themselves didn't actually budge, instead I had completely ripped the paint off of the wall! If you actually follow the instructions instead of just instantly applying them and slapping it onto your wall, then you'll experience an extremely strong adhesive. I've also happily mounted two Google Nest smoke alarms (which weigh around 1kg each) using just 2 permanent strips for each. One mounted on the ceiling, the other against a wall. Several months later, both are still perfectly in place with no signs of detachment. Note: I'm talking about the Unibond PERMANENT strips (with the red plastic on them), not the Unibond yellow ones. I'm thinking some of the reviewers might be confusing this product with the yellow non-permanent ones, which only work for extremely light items (think no heavier than a standard TV remote). Now, if the instructions on the back of the packet aren't clear enough, here's my own step by step instructions and tips for getting a "permanent" stick: ================================ 1. These strips work best on a flat, smooth surface, such as a concrete wall. Be warned that there's no real method to remove them (note the word "PERMANENT" in their name) unlike certain other strips - if you're mounting something onto a wallpapered wall, they will very likely tear the wallpaper off if you try to remove the item, or if the item is too heavy. 2. When using these strips, first make sure the two surfaces (i.e. the wall, and the thing you're mounting) are clean and dry. Surfaces can accumulate dust, lint, and oil from your household, and this can prevent the adhesive working properly. Suggested cleaning methods: - (easiest) lens cleaning wipes - ideally ones containing alcohol. those of you who wear glasses may find this the most convenient method. - 99% isopropyl alcohol (https://www.amazon.co.uk/gp/product/B003D8SDSW) - one of the best options as it's generally safe for most surfaces, shouldn't cause any damage to electronics as long as they're turned off, and generally evaporates within a few seconds of application without leaving any residue. if you don't have any, buy some! it's extremely useful for cleaning electronics without the risk of water damage. - methylated spirit - not exactly common in most households, but is recommended by unibond. be warned that methylated spirit is highly toxic and can damage certain materials. NOTE: when using liquids to clean the surfaces, use a fresh microfibre, or lint free cloth (e.g. AF Safecloths https://www.amazon.co.uk/gp/product/B001J8F7OQ/). other cleaning cloths can leave small amounts of lint or oil that can prevent the adhesive working properly 3. After you've cleaned and dried the surfaces, you should apply multiple strips onto your item and evenly distribute them depending on the size and weight of your item. General rule of thumb - the more strips you use, the more likely the item will stay mounted. Avoid pressing too hard when applying them to your item, or you'll have trouble removing the red tape once you're ready to mount it. - For small items (no wider than a normal sized mug) that weighs less than 1kg, you may be able to mount them with just a single strip in the center. (e.g. small smoke alarms) - For square(-ish) items such as routers, you should ideally place one strip in each corner of the item, plus one strip in the center - this ensures the weight is evenly distributed. - If the item is around the size of (or larger) than a sheet of A4 paper, and weighs at least 1kg, then you should place at least 3 or 4 strips across each edge of the item (similar to mounting a poster with blu-tack), as well as 1 or 2 strips in the center (to prevent too much weight going to the bottom strips). 4. Remove the red tape from each strip, and then carefully press your item onto the area you'd like to mount it. Once you've positioned it correctly, firmly press your item against the wall, making sure to apply pressure to the points with strips behind them. Keep the item firmly held against the wall for at least 2-3 minutes (if the item is large/heavy, more time is better), and apply a lot of pressure as the adhesive seems to be pressure-activated - the more pressure you apply, the stronger it will stick. 5. After enough time has passed, slowly release the item. - Upon releasing the item, watch it for a few minutes to ensure that it's staying put. If the item starts to come loose from the wall, re-apply pressure to it immediately. You may have needed to press it harder and/or for a longer period of time. - For best results, re-apply firm pressure for several minutes after a few hours have passed, this helps to ensure the adhesive has good contact with the surfaces, and will sustain good contact after it settles. - If the item is heavy and has a lot of frontal weight (e.g. a shelf or cabinet), you should place something underneath it that can support it's weight, as the adhesive may need up to 24 hours to settle enough to support it. ================================ If you follow my instructions and consider my tips, then it's likely whatever you mount using these strips will be stuck there for good.

Update 2023: installed in 2019, it still lasts on the car after 4 years! We’ve fitted the number plate on an Astra which as you can see it needs to be bent, requiring a lot more resistance from the adhesive. So far it’s lasted for 2 weeks under mixed weather conditions and motorway speeds so quite happy. Seems solid. Used whole package just on the front plate to be sure. Pro tip: red layer is hard to grab to pull off, but using tweezers makes it much easier. Don’t attempt to do it just with your fingers as you’re likely to remove part of the foam as well.
