Ok, so admittedly I've only had mine about a year, but considering they were recent imports that looked like CRAP when I got them, I feel pretty good about my experiences so far. First off, I ONLY handle mine during the day. After nightfall, that's it, hands off. That being said, during the day, I've never been struck at. Not to say that they're always zombies during daylight, but much more sluggish. After dark, mine are a pair of heat-seeking missiles. I don't know about other dendro keepers, but mine also respond differently to my wife and I. Sometimes I'll go in late at night and just watch the pair (since they just sleep all day), and if it's just me in the room, they just go about their business, looking for ways to escape. But as soon as the wife comes in; BAM! They both stop whatever they're doing and watch her until she leaves...then right back to it. One has even struck at her through the glass before. My retics are very similar. Can't speak to what they'd do with others around, because generally if the reptile room is lights out, company's not here. Long story short, I love my pair, use a stick with them when I need to get them out, leave them alone otherwise, and I've never had any problems. Hope that helps.
