I will refrain from mentioning names - that isn't the point of this. I just want to share my experience (and frustrations) with those of you wishing to follow my footsteps.
My son rides a GS, and I ride an LT - neither stock seat worked for either of us. Last year, I bought an aftermarket seat from a forum member - which still wasn't enough for me, so I decided to pursue a personal custom, rather than someone else's - & my son went straight for the personal custom.
I did my research here, and on other sites, and my son was on the phone - I had a second seat & he did not.
I placed my order in February & got a production date in mid-May - then sent my second seat in early March (actually, had my Office Manager send it for me). My son could not accept a delay like this, and found a vendor who promised a two week turn around. He sent his seat in, and got the new one back in less than a week! I was impressed, but have purchased from that manufacturer in the past for other bikes & found the seat to be too hard for me, so I left my order in place.
I decided to upgrade my order slightly in early May - a little over a week before my "production date", and after four attempts at contacting the vendor, finally got through and was told they were awaiting my seat. Fortunately, it was sent by FedEx and I had a signature, date, and reference number. Lo & behold, there was a seat being held under my office manager's name, waiting for an order!!?
If I had not called, I would have lost my production date, and probably not had my seat before Christmas.
The production date arrived, and the company rep call me to correct a few issues in my request, and the seat was shipped yesterday (that's 13 working days in process - 4 longer than it takes to produce a Positron Emissions Tomographic medical scanner?)
All representatives from the company were (stressed) pleasant on the phone, and worked hard to fix the issues, when identified - but the entire effort amounted to a frustrating consumer effort. Based on my research, the company I chose was the top of the heap, but I really think there's an opportunity for someone offering better service and attention to detail.
