Love using the Big Tabs...more room to type info on inserts and they don't fall out of the plastic tabs. And, the dividers are made from 30% post-consumer recycled paper!
I don't really have any problems with these tabs. They print out and insert just fine. I do like that I can split in half to use when I only need a few. My only thing is not being able to use the rest of the tab inserts in my printer once I have already used a few. But still a very good product.
Our company has used these tabs for years, so we buy them in very large quantities. My biggest complaint has been the "unique tab design" which makes it hard to use multiple packs for various projects. I do like the reinforced edges which are more durable than other brands I've used in the past. The durable tabs make them great for long-term file and record storage.
