I also just received a pair of mis-collimated Zhumell's. But it didn't take long to get them into perfect collimation. I've been drinking in amazing views of Comet Holmes the last couple of nights. It's unfortunate (but workable) that the problem lies in the weak frame that support the two large optics. The frame bends under force misaligning the two optical trains. This property also makes for an easy "adjustment". It took me about four twists and pulls on the two sides to bring them into collimation using a bright star for reference. Since that time they have remained collimated under normal gentle use. Personally, I'm thrilled that a mere $69 has delivered such a wonderful observing capability.
