These are very accurate and there's not a whole lot to say because if you're buying this you know what they are for I personally depend very heavily on reviews that are posted on Amazon, as do many other consumers. I not only read what reviewers say, but look to see what their pictures reveal about a products true quality and description. I aim to not only feature the products I review in many different aspects, analyzing many qualities, I also provide my own opinions on ALL the good AND bad experiences I have with the product I review. I take time to learn and use a product as it was intended before I review it, and I have used this specific product thoroughly. My rating system: 5 - Met all my expectations. Was described and pictured perfectly. Exactly what I wanted and needed. Extremely useful product and a great value. Would recommend to family and friends. 4 - Very good product. Exactly as described. May have a minor flaw, mentioned in the review, that does not detract from the products perceived value. Would recommend to family and friends. 3 - Average product. Not exactly as described, or misleading advertising or product pictures. Possibly substandard build quality, or something else explained in the review. Would mention as an option to family and friends, but not recommend. 2 - Wouldn't recommend this product. Poor build quality, not close to being as described. Flimsy and fragile. Difficult to use due to product flaws. 1 - Do not purchase whatsoever. Usually only given if product lasts only a few hours/days/etc. I do not leave 1 star reviews without contacting the seller. I will be returning the product. I did NOT receive ANY discount for this product. I simply enjoy reviewing every one of my purchases.

I got these for modeling, holding things together with weight. I've discovered that you can also use them in wood working. The measurements are 1 inch across, 2 inches on the side and 3 inches wide so you can use them to measure table saw heights, squaring things, and router sets. The ones I got were a little greasy at first, but when I was using them for railroad modeling, I wiped them and used wax paper to keep the gunk off my buildings. Very useful.
