Cleaning and lubricating your tripod, no matter what material it's made of, will extend its life. The biggest point of contention seems to be over lubrication, so here's where I'm going to attempt giving a definitive answer for most tripods and ball heads.
My B2 ball head has had an issue with drift since purchase, and after months of dealing with it, I felt it was now time to finally fix the issue. The G2 a high quality, low profile ball head with huge capacity and smooth action that punches well above its weight. It compares favorably against more well-known name brands even if you take out price as a factor.
I only had this tripod for a week before returning it from whence I bought it. I was so thoroughly disgusted with it after receipt, then after one use, that I didn't bother to take photos of it before throwing it into its shipping container and sending it back.
