I do a lot of mailings for my company so I am very particular about the labels that I use. I need something that I can use with word docuement, merges easily and prints great. Avery does all three of these and more. I know when I first started using them they were a little difficult to use, the biggest problem was the labels woudl start to come off while I was printing them. The company must have gotten a lot of complaints because they came out with a newer version and I have had no problems with them coming off while I am printing the sheets. They work really well with all different programs and if you use there printing program they make it very easy to change and personalize the labels to fit your company. I am most impressed that the company recognized they had a problem and fixed it!. Great product I even now use them at home for my Chirstmas cards.
