This is precisely what I was looking for in a check book holder: something functional, well made, and unassuming in appearance.  It's a basic, no-frills checkbook holder.  Other than one very small pocket into which you could slide something thin, like a credit card, it's very much the same layout you get with the free, cheapo vinyl covers you get from the bank.  The leather on these, however, is very nice.  It's supple, soft to the touch, and yet so far has proven to be rather durable.  I think it would likely scratch if subjected to abuse, but I've run into no difficulties along those lines.

Another reviewer mentioned that he had to trim the backing on the back of his checks to get them to fit.  I had this experience as well.  It took about 12 seconds.  The dimensions and inside workings look to me to be entirely standard, much the same as freebie checkbook holders.  I think the difference in having to trim the check backing with this checkbook holder comes from the fact that the leather does not stretch and give like vinyl.  I suspect that over time I'll see a bit more give and this will become less of an issue.  In any event, it's the most minor of inconveniences, and it's certainly better than having your checks slide out because the holder isn't sufficiently snug.

In sum, if you're looking for a basic checkbook holder with quality leather and an understated look at a very reasonable price, this would be a good choice.

UPDATE

Having had this now for well over a year, I can confirm that the leather has softened up to the point where new checks slide in easily with no need to trim the backing.  It's holding up very well.
