I'm a by hand guy myself. I have tried those tube gadgets and find I need to put an uncomfortable amount of pressure on the queen to immobilize her. They are very squirmy so she has to be pinned down with her legs spread out beside her. It is almost like the last phase before she is squished. And then half the time it seemed like by the time I had the correct pressure to immobilize her, she had squirmed enough that her thorax was not lined up with the hole. I find it much less stressful on myself (and it appears the queen as well) to do it by hand. I know it can seem pretty daunting the first time you do it, but if you practice on drones first, you can be comfortable before doing a queen. Here is a video I put together many years ago.
