Feature:
The built in "clips" are convenient for the f 10's and 12 but you need to take your time in set up to avoid possible cross threading or stripping. The plactic clips for the f15's (pencil condensers)could be heavier but so far no problem.

Quality:
The casings are not in the same league with the D series but they can take a hit (more than once) and keep on working...I really can't say that about the eight or nine 57's I have sitting in a box in my garage.

Value:
I've yet to see a kit in this price range (or even $100 more) that even comes close to the performance and reliability.

Desirability:
Form follows function. I does the job very well and is not obtrusive. Yes it's not the "classy/flassy" look of an RE 20/27 or a Senn. 421 but for the weekend warrior that want a dependable no hassle set up and good to great sound (depending on your system and your tech) and not have to come up with the extra coin of a shure kit. In my world thats as sexy as 36-24-36.

Sound:
while the sm57 was my mic of choice for snare(live sound reinforcement)upon replacing it with the f10 I found a new sense of depth and fullness that was missing from the 57 and definately lost the hi-hat bleed. The only mic I would consider a step up (in a reasonable price range) would be the Audix D1.

Ease of Use:
I find the set up very simple ...want more bass aim mic closer to rim want more attack ...aim a stick impact point..or vary in between to achieve your sound..No brainer.

Support:
I have not had to deal with audix concerning the F series mics but I did have an older large diaphragm condenser that was years out of warrantyn that went dead and they swapped me a new one with warranty at a ridiculous price and in a very timely manner. Probably one of the best companies I've ever had to deal with.

Overall:
I expect to keep this set until I'm done using it and at this point if it was lost or stolen I'd buy exactly the same again. It's better than just "bang for the buck" mentality. I've been a tech since 1983 and a road musician for 15 years befor that. Ive worked every type of show from acoustic solo guitar/vocal to 80 piece Philharmonic orchestra and every type of live show in between. I've used 421's (great sound/terrible clip) Still use RE27's but for drums it's f series for my B rig and D series for my A rig.In general I like everything about the product execpt for the cheaper clips. The D series clips are great ..hard rubber instead of hard plastic that breaks.
