I almost bought this model because I'm tired of buying $30 trimmers twice a year (I have 5 now) and just couldn't face paying for this Carl trimmer although I came close. Have a look at the new Carl 13715 Trimgear Industrial Trimmer. It's more compact (the second 6 inches slides under the first 6 for portability) and offers most of the features of this model for virtually less than half the price at some places ($93). It cuts all matter of material (and 5 sheets of cardstock at once), and has a self-sharpening blade that "returns to start" after cutting. It's a tidy little package that's portable.
I'm waiting for mine to arrive tomorrow and can update this review then. Really looking forward to it. After trying 5 trimmers, I'm looking for one that will last for awhile.
First, I should say that I don't have the DC-210; I have the RT-200, which I believe is one step down. My only real beef with the Carl trimmer is that the rotary arm is stationary - it doesn't lift, like on most trimmers. It may not seem like a big deal, but it can be a real problem at times.
First, it makes it very difficult to cut small items - there is just no good way to really position them for the cut, since you can't get under that arm. To make small cuts even more difficult, the rotary arm on mine is not transparent, like almost all rotary trimmers are. (It looks like maybe Carl learned from that mistake, since it appears that the DC-210 does have a transparent arm. Keep this in mind, though, if you are considering other Carl models.)
Second, there are times when I'll need to trim something that might already have a little bit of adhesive on the backside. Even just a teeny bit of adhesive can cause the item to stick to either the cutting mat or the underside of the rotary arm. Since the arm is stationary, I've actually had to use tweezers and little tools like that to try to pry out my paper. By the time I finally get it out, it's often just ruined anyway.
Also, in situations like that, if the paper leaves any residue of adhesive under the arm, it is a real pain to try to clean it out. On most trimmers, you could just lift up the arm, and wipe the adhesive off. With the stationary arm, though, I've had to just do cut after cut after cut on scrap paper until the residue was finally worn off.
I love this trimmer! It cuts through chipboard and multiple sheets of cardtock like butter. I make a lot of books with my zutter so this saves me so much time and was worth the price (which I was worried about).
I have very thick chipboard that I use for books and this cut through it with no problems. I was amazed. It did take 2-3 passes on the trimmer, but it cut it clean. The trimmer locks down onto your paper/chipboard and it will not move as you cut. Best trimmer I have found to cut thick items.
I have the larger 15" version of this trimmer and I absolutely love it. I needed something that could cut cleanly through heavy weight chipboard and this does the job with ease. Very highly recommended!
