It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on callers' favorite stocks at rapid speed:
Sierra Wireless: "Good company, kind of does a lot of the stuff that you want in communications, but if I want communications, I immediately think about Broadcom, which has done nothing for ages and is a better buy."
Shopify: "OK, now, Shopify itself is a little pricey stock. I know that Andrew Left at Citron [Research] has said some very negative things about it. But it is still an important small- and medium-sized business website, so I think it's fine. I'm not going to pound the table on it after Left's comments, but I'm not going to tell you that I think it has to go."
