Good for your money
First time using this and it is the BOMB. I love it and it is easy to use and really does work. It helps with the temperature and the draft.

Really good at closing gaps
Really amazing product. Normal caulk is so messy and a pain to mould and isn't very renter friendly. Had some issues with roaches and was able to seal a lot of the small gaps in my house with this and it looks like it stays firm but should come out easily when moving out! Sometimes need to use a lot more bead lines than expected but it's easy to build off from.

Easy to use
Worked great for quickly sealing up my baseboards for pest management in my apartment Iโm renting. Only problem is I bought the white twice, and they are two different colors.

I no longer have to hire someone to do the caulking!
Finally, a caulk I can use, and the finished product does NOT look like a 6-year-old caulked it. I used this caulk cord inside my cargo van conversion and am so happy with it. It has not lifted like most all the caulks I've used in the past. -great value considering I'm not ripping it out and hiring someone to do the caulking. -the durability, thickness and lengths are all just what I would except of a quality product. -color is great doesn't fade. Thank you so much for turning this 60 something nomads diy caulking projects into something I will not rip right back out and hire a handy man to redo. I would and WILL purchase again

Great product
I have been using this weather stripping for years. It is so easy to use (no caulking gun) - just decide how many strands you need for the right thickness and then snip the ends to what ever length you need. Very pliable and easy to stuff into cracks and gaps. And just as easy to remove. Excellent product!

This keeps the tiny ants out
Although I have a pest control spray every 3 months, when it's a rainy day those pesky tiny ants come in my kitchen window. I have shiplap walls so they come in through the grooves. I also can't fit a caulking gun into the area where I want to use this. So I tried this caulk rope. It seems dry at first, but when you work it into the gap, the warmth of your fingers softens it up. I only needed to use 2 strands and it was more than enough to go completely around the kitchen window, plenty of it left over. I store the leftovers in a ziploc baggie to keep it fresh.

It isn't that great
I needed to seal some gaps in the windows at the store I lease "property management says windows are my responsibility". It isn't that easy to work with and doesn't stick in the corners very well. After 2 months it has started to fall out so now I'm back to shoving it through the gap with a putty knife and hoping it stays. I followed the directions on the box. At least it isn't very expensive, since I refuse to spend a lot of money on something the building owner should handle. When it stays put in the gaps, it does cut down on drafts.

Old product
This I received because it looks so interesting and so usable it was like dried clay. It wouldnโt stick to anything and messed up and wouldnโt even stick to each other. They sent me an old box I guess cause it was terrible. They messed up to take back. It was in a wad time I got through. Shame on you guys for sending me a old package, but I needed it so badly.

Excellent product, used it to seal my A/C block off plate on my car, and well as to seal the heater blower.

Great for drafty windows
This stuff is awesome. I wish I had known about it years ago! My husband and I started caulking our old drafty windows, but it was a real pain and was making quite a mess, which was stressing me out. Then I found this stuff online! Iโve been putting it on the windows now and it has stopped the drafts! Amazing! You have to peel it slowly, but it comes off in great single strips. Just have to be gentle. Only complaint is that I wish it was white, so it would match the window frames and be less visible. Not really a problem though in the long run because it just peels right off, so I can easily remove it in the spring.

Excellent product and very flexible
Excellent product but took a long time to arrive. It actually came all the way from America which explained why it was so expensive I presume import duty.
