Not too bad. My spider's only came out when he was about to strike, he would miss big time here and there. My bee on the other hand, he does some weird moves sometimes when you are holding him or when you put him back in the tub. What he does is puts his head up pretty high then slowly starts turning his head upside down or tilts it. For someone that doesn't know to look for that, they might not notice anything weird, but anyone who knows about the spider wobble would notice it.
Every spider has a slight wobble at the very least. Those ones would be like my spider, that it only shows when prey is introduced, and even then you have to know what to look for.
