What a difference these made!
With a previous employer, I frequently was involved w/ public meetings requiring multiple display boards. Once we hauled over 20 wooden easels around to meetings over several days. When the firm purchased a number of Instant Easels, the setup/tear down time was cut in half (not to mention the splinters, frustration, etc.!). I remember the biggest downside being the broken clips and difficulty in finding replacements. I wasn't responsible for this, so didn't think much about it at the time. I just knew I didn't want to be in front of a client with a duct-taped clip on my easel!
Years later I am at a smaller company that recently had a meeting where a couple of the Instant Easels were used. One of them had a broken clip, so I looked at Staples website to order replacements and they weren't shown. I called the store to see if they had them in stock and they acted as if no one had ever asked about this before. I got on Quartet's website and the only mention of clips is in the comments section...people complaining about the difficulty in finding replacements when they break. Enough time has passed...I'm a big fan of the product, just get on the stick about making replacement parts available easily through your distributors!
