I personally LOVE these.

First these were delivered so fast. They were here several days before I thought they would be. The packaging was great and i loved them. The best thing about them is they are so big. It gives my little man about 26 feet of play area. Most are 16-20 feet that I seen. I wanted him to have a larger play area. They give him the extra protection he needs on our hard floors. I am actually thinking about ordering a second set for upstairs as well. They are not the thickest ones I found but they work perfect. He has just turned 10 months I have had them over a month. He has been standing and falling on them for weeks and there has been no tears  shed. So that tells me they are thick enough. He crawls and walks all over them.
With that said.. He has figured out they do come apart lol. But they all come apart and that does not seem to effect my opinion. We tell him no and he laughs at us. I try to keep him with enough items to keep him playing. So far over all no problems.
I love them and I think its the best investment ever.

But I personally love these.

PROS:
- No bleed through
- never dries out - even if you lose the lid
- rich vibrant colors
- will never crinkle the paper like some highlighters with excess liquid/ink

CONS:
-  Cap doesn't secure very well to the other end while using it (but if you lose the cap, it's okay as it won't dry out)
-  Doesn't completely cover text you are trying to highlight (think crayon type coverage)'hower text does stand out, which is what you want!

I've never had a problem with the 'waxy' coverage like some reviewers have mentioned and I use them every day at work and bought a set for home use.

This may be one of those products you either absolutely love or don't like at all, depending upon your personal tastes.  I've had co-workers try them out, and all were intrigued (these are quite different than other highlighters) and all, thus far,  seemed genuinely impressed and liked them a lot.

I actually own a bunch of different sizes.  Basically I love these, BUT, they are kinda pricey.

I purchased these for a small office. I would give these a 5 star rating but since 5 stars would mean I love it I just can't say that I love these.  My Grandmother taught me you can't love an inanimate ofject.  I really do like these though.  They have a nice weight and length to them and they won't get thrown away by any of the staff!

These were just what I was looking for.  There are sooo light, which I personally like, but I think some people would think they're fragile.  They are thin, which I also like, but people notice them.  I wear them soo much and they are withstanding my abuse, and I'm surprised.  They probably are about the size of the palm of my hand, or a tad smaller.  I just love them.
