I bought this on the release date and assembled it that day. Afterwards, I displayed it indoors for two or three weeks before storing it in its box. More than 10 years have passed since I built it, but the articulation is still fine. I don't think any parts are broken. I apologize if there are any I haven't noticed. If you let me know, I will add more photos. I've never transformed it into Wave Rider mode. I'm still too scared to do it, even now. Please consider this a junk item. Thank you for your understanding that this is a junk item.
