Let's be real – no one gets giddy about aluminum foil tape. It's like the socks of the home repair world: necessary, but about as exciting as doing taxes. BUT, let me sing the praises of 3M Aluminum Foil Tape 3381, because this ain't your bargain-bin tape, folks. It's got superpowers I never knew aluminum foil could possess ...Why you NEED this tape in your life:HVAC's New Best Friend: Leaky ducts are the air-conditioning world's villain. This tape? It's the superhero! Seals those gaps like nobody's business, saving you on energy bills and the shivers in winter.

Patch it with this tape. It sticks to practically anything, and its durability defies logic. Now if only it could make me handy enough to actually handle bigger home improvement projects...A Cold Weather Warrior: The description says "cold weather," but honestly, this tape is tough as nails year-round. Rain, sleet, heat wave – it doesn't budge. Mother Nature might as well take a coffee break, 'cause this tape won't let her ruin your repairs.Romance Revitalizer? (Seriously, hear me out!): Spouse complaining about squeaky cabinets? A "strategically" placed strip of this tape quiets that hinge better than flowers.

A makeshift shelter, a weapon patch-up... This tape's versatility could buy you precious time against the undead.

It's made my DIY attempts less disastrous, kept my house's temperature regulated, and might even win me brownie points with the spouse. Now, where did I put that wobbly chair...

The tape arrived as described with no issues I bought the tape to use to cover holes at the bottom of my HVAC unit to keep critters from getting into my crawl space and to secure ducting to vents I replaced. It has worked great, and held up, wonderfully even in the rain. It is also handy for any unexpected duct repairs.The tape is a quality product made by 3M that has good thickness and adhesion. I have no complaints as it met my expectations. I would recommend this product to others.

Used this along with insulation wrap, as others did, to wrap the output hose of a portable air conditioner. Until I did this, the device was pretty much useless because the hose radiated so much heat that it negated the effect of the air conditioner.Fastened the insulation in-place with this tape. Working just great! NOW the air conditioner actually COOLS the space!I did not rate "easy to remove" because it's not intended to be removed easily. It can probably be removed fairly easily however, depending upon what you stick it to, but I didn't rate this.

I've used other brands of metal HVAC tape before that were much easier to use. This one has good strong adhesive, but it's real thin so when you pull the paper backing off, the aluminum tape part actually wants to curl up on you really quickly and badly. It sticks to itself and makes a mess. I had to throw some away as a result = waste. I finally learned the trick was to just pull the paper back as you lay it down.So it's usable, but it's a bigger pain than other brands I've used before. I think maybe the other ones I used had adhesive but it was just like duct tape - already on it and you rolled it out as used. I don't remember the paper backing step before.

But the price has nearly doubled over the last year, nothing against the product, but it's worth looking around at the price it's at now, the rating is for the product itself, not the value.

It is very good metal tape.

Good quality

This has great adhesive qualities. It stays in place. Tha backing peels off easily.
