As with the Alvin Cutting Mats,I purchased this for my wife and her crafts. I have not heard any complaints so I assume it's working well for her.

I purchased this cutting board and another one with different color feet to replace cutting boards that have been in my cabinet too long. I primed both of them with mineral oil. I plan on using one board for veggies and another one for meats. Interestingly enough, even though the descriptions of them are the same (aside from the different colored feet), this one is not quite as thick.

I've purchased some cheaper ones from Ikea and they immediately drew cuts and gashes. These mats are flexible and long lasting.

I really like the quality of this item fits great in my kitchen and like the different cutting mats for each item so there is no cross contamination! Thx Amozon

I purchased a set for my 2016 Focus to replace the thin stock mats.  I wasn't willing to pay $100+ for custom molded mats. These things are thick but are not too difficult to trim.  I needed quite a bit of cutting on the driver mat as my vehicle has a large dead pedal area and I wanted to make sure there isn't a pedal interference (I have a manual with a clutch pedal).  They have a bit of a smell from the production process but that will dissipate with some time.  Overall a good product.

These are just what I needed as I get more serious about photography.  Good quality control evident in the cutting of both sizes that I ordered.  The box in which they are packed is perfect for compactly storing and protecting the mat sets you don't use immediately.  It is important to carefully remove the cellophane in which all the supplies are wrapped within the box.  Acid free materials are NOT available at my local Michael's store.  Price seems fine to me and I was grateful I didn't have to buy a huge quantity.  Seeing how good these mats are makes me feel vindicated in the decision to NOT buy a mat cutter deal with large boards that are difficult to transport and store.

I was surprised to find that I needed to purchase the mat separately, but I am pleased that if I never need to replace it, I can. Very well marked. I like it!

I got this cutting mat as a gift after years of using cardboard, stacks of papers, plastic table tops (aka anything) as a cutting mat for my paper cutting antics. It's thick and the gridlines are extremely useful, the coloring of the cutting board itself is really pleasant and matches my desk, and it stays flat so it's very easy to carry around and transport. The only thing I dislike is that it doesn't really "self heal." I've used some other cutting mats that are made of some sort of silicone blend that almost fuses back together after you've cut it, which I would refer to as "self healing" but this one doesn't really do that? Additionally, it's a b* to clean. After a few projects that included ink and stamping, my mat now forever has ink smudges, sigh.. But all in all, it's a nice cutting mat, especially for people who are averse to having a dark green/black mat and would like something softer and easier on the eyes.

Excellent cutting mat! I use it for everything from cutting balsa wood with X-Acto knives to trimming tissue with a razor blade. Good healing and every layout aid you might need. In the past I've used very expensive mats and they were no better than this one. Highly recommended.

I bought this hoping it would be able to cut through matboard to make chips for a game I'm designing and it works great!  I was a bit worried since the matboard is significantly thicker than paper or cardstock, but it slices through it with ease.  I recently went out and picked up a different brand in a different size tonight 'cause the local craft stores didn't have this brand in a 3/4 inch size.  The other brand was garbage.  It couldn't fit the matboard and wouldn't even cut completely through a piece of standard paper!  So I'm returning it and ordering this one in 3/4 inch size.

This really is a very good cutting mat.  I like the size and the weight of it. Very flexible yet very durable.  Still looks new.

I purchased two of these for my double porcelain sink that has seen better days.  I wish I had done this years ago!

The mat provides a nice, soft landing for dishes dropped into the sink by my kids, and the holes in the mat allow it to drain.  I cut a hole in the garbage disposal side, it was easy to do with regular kitchen shears and I appreciated that I could place it wherever I wanted.  The grey color is very nice, I was worried that it was metallic or glittery but it is not.  The mats rinse easily and have not stained yet, even with art projects and acrylic paint.

I am disappointed that the mat is less opaque than I wanted, I can still see the sink scratches that have been making me crazy.

A very nice cutting mat. Great customer service from the seller. Measures 17 5/8" X 23 9/16" as stated in the description but advertised as 18" X 24"

I already had a 24x36-inch Olfa mat and a small, skinny one by Fiskars that I find useful for certain projects.  However, I like to cut my own unprimed linen for adhering to birch panels or for wrapping/stretching on stretcher bars for large oil painting surfaces/canvases.  So, when offered an opportunity to try out this Adir brand of self-healing mat, I chose their largest mat -- a 36" x 48" model.

When I first removed it from its packing and unrolled it, I was a bit concerned about it learning to lay flat, but it was perfectly flat within a few hours without any need for me to attempt to warm and straighten it.  There was a slight odor when it first came out of its protective plastic bag, but that smell went away quickly.

For my own purposes, the Adir mat works great.  As I mentioned above, I use it for cutting linen (with a razor or rotary cutter) in preparation for making artist canvases/panels and so the measurements don't have to be dead-on for me.  Which is a good thing, because these mats seem to lack accurate measurements.  On the 48" side (lengthwise), the measurement is nearly exact -- just off by 1/16" for that long side.  However on the shorter side (36"), it's off by nearly 1/4" which is fairly significant.  I'm not sure if the inaccurate measure markings are an issue with all of the mats, or only this size (or perhaps even only messed up printing on some, but not all, of them).  I wanted to mention this, though, for those who require exact measurements and were planning on using the mat to find those exact measurements rather than using some other measuring tool.

The self-healing function of both sides (green and black) works very well.  Because this large mat is quite heavy, it stays in place nicely on my work table.

The mat has measurements in inches on all sides and metric measure on one long and one short side.  There's also an inch-measure directly through the center lengthwise and widthwise.  The entire mat is divided with vertical and horizontal lines into 1" squares which I've found to be fully "square" to help with making 90 cuts (good corners).  In the mat's corners, there are marked lines of various degrees to help you with angled cuts.

Again, since I'm using this mat primarily for its self-healing capabilities and large size, it's working ideally for my needs.  Just be aware of the inaccurate measurement issue -- particularly with the short side.  I would give the cutting function of the mat 5-stars but the measurement issue brings down my rating to something more in the 3-star range or lower.

I was provided a mat for reviewing purposes.

Very nice cutting mat. Heavier than I thought but that's a good thing. Thanks!

This mat was easy to install and cut to size. Thickness is good and seems like a durable product, it's ok for the price

This is a pretty nice mat that I've used both on my carpet (giant area rug) and wood floors with no damage to the flooring. It's made of some type of heavy-duty material that's pretty durable feeling, and mildly squishy. It has never moved or slipped on me, and it's quite difficult sliding my equipment around the room on it even if I intentially want it to.

There are two sides to this mat which confused me at first since I didn't know which side was supposed to be face down, or up. One side is smooth, and the other is bumpy and coarse. According to the photo which came with the packaging the coarse side with the logo is supposed to be upward (which makes sense as it causes traction for equipment) and the smooth side faces down.

I've noticed the equipment I use with this mat (<a data-hook="product-link-linked" class="a-link-normal" href="/Schwinn-A40-Elliptical-Trainer/dp/B003UNVU1M/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Schwinn A40 Elliptical Trainer</a>) leaves indentations in the mat where the footings are, although this is not a bad thing. Also, since my Elliptical Trainer doesn't need the full length of the mat I fold one section (each section is about 1.5 feet) on both ends underneath to keep it contained to a smaller square. Because of the folding it causes a little pocket which I've tripped over once or twice, but this is more because of the tiny space I have it in, as well as my lack of balance and stride.

If something ever happened to this mat, such as an epic chain saw accident or a burglars need for excellent exercise equipment mats, I would buy this again. For the price the quality seems exceptional, and it's convenient being able to fold it in the event I ever replace my Elliptical without having to worry if the new one will fit my mat.
