It seems these days that Meucci is perhaps one of the most polarizing topics in pool/billiards. (We won't start on aiming systems or LD shafts). So ...
Good:
Back in my shooting days (70-80s), many of our locals (Pittsburgh PA., USA) who were considered good sticks, felt that Meucci was far and away the best you could get outside of a custom built cue. (There weren't as many competitors, and the Internet hadn't been given to us by Mr. Gore yet.) I think they still make a great *looking* stick. I personally liked the feel of the Huebler back then, so it became my main stick for over 30 years. They have put a TON of money into marketing, as well as promoting the sport and sponsoring various events. Apparently Bob (the old man) has always had an open door policy, and is approachable by just about anyone.
Bad:
Many of the older players seem to feel these days that the quality started going downhill in the late 80s or early to mid 90s. Inserts lifting, shafts splitting, ferrules chipping, and generally becoming a mass produced "cheaply" made cue. (while still commanding a higher price.) IIRC, Bob retired, or at least spent less time in the shop - and it got really bad for their reputation. I've heard (although I don't know myself) that he (Bob) got back into the manufacturing business in the last couple years in an effort to address the quality control issues. (Personally, I hope he is successful)
Meucci grew pretty quickly, and when the most recent "boon" hit (think 1986, Color of Money) .. the company grew and grew... and grew - to the point where the individual craftsmanship was basically lost. Now mass-produced on CNC machines ... they kick them out by the tons.
I think in this day and age, the bottom has dropped out of the market for these kinds of sticks - and people willing to spend $300 or more on a stick want a more personal touch.
Just all IMHO,
