I think this adhesive is great! It is much easier to use then the Tombow Mono which I always trouble with. And the dots fit into the same applicator as the Mono. So you don't have to buy a new applicator. I use to use Herma Dotto but the Tombow is so much easier to reload! For ease of use this brand deifinitely has my vote! Plus, it works really well. I haven't had any trouble with it not sticking or things coming undone. I definitely recommend this product!
I have tried several different taper runners ... and by far Tombow is my favorite. I know make a point to stop and us my M's or J's coupons on refills if nothing else scrappy catches my eye, may only be a small $$ saving but having refills on hand is important. My kids have even developed a strong liking for my tape runner and they use it for their school projects quite often. I have NO luck using the liquid adhesives ... and yes pop dots and glue dots have a time and a place but my Tombow is by far the most used.
This refill is very easy to use, though I wish it saved a bit more on plastic. For an old-school scrapper like me, who still uses glue sticks for most of my adhesive needs, these little rollers are amazing - quick and so easy. It seems a bit expensive, though, compared with glue sticks - but the results are better and more durable. For LOs that won't just be sitting in albums/sheet protectors/frames, the rollers are great.
