This is my third. I have two others that are over 8 years old with nearly daily usage. Sure it's soft but the hard polycorbon one I got from a certain online seller started cracking after 2 years. These are the ones to get if you want a long lasting one.
I purchased what I wanted. No Staples employees were available to help me other than a cashier and a manager who was not particularly interested in helping. No one was available to answer questions other than the cashier. I coordinated with another potential customer who had the same problem as me together we helped one another as well as we could. I found most of what I bought by myself.
