solo/speed bleeding caliper valves
Anybody here use them? I'm wondering if I should put them on both sides of the caliper or just one. Any long term use problems?

I have used speed bleeders for the past four seasons and love them. It makes bleeding after an event a single person process and very easy. Never had a problem.

So....you say "both sides of the caliper" so I'll assume you have some kind of fixed caliper with a couple bleed valves on each caliper.
Yes....in order to properly flush/bleed your system you'll need to bleed fluid from both bleed valves (inside & outside) on each caliper or you'll likely leave some old "moisturized" and tired fluid in the caliper.

Yes, you need to replace every one of the valves.

I tried them once 10 years ago, and had one leak after only a few events. I purchased a pressure cap and a nitrogen bottle, and have pressure bled ever since. I'd prefer to use any pressure method (ie GM cap, Motive, etc) over speed bleeders or vacuum bleeders.
I acknowledge many folks love them, but you only get one chance with me, and it didn't work out.

OK, so I'm feeling a little ripped off by LG Motorsports after they shipped me two valves for their "single axle package" which includes two valves. You sure you need 4 per axle?

Well.....you didn't say what kind of car or BBK you're running, so I looked in your profile for a clue. Nada.

I have speed bleeders in my Z06 (2 in each caliper
).I also use a Motive Power Bleeder.
I pump it up to about 10 psi and it pushes fluid through the speed bleeders with no problem.
Like David says, he uses nitrogen. Like many others here, I use my Motive Power Bleeder only as a pressure source (I don't put any fluid in it).
The concern is that you're pushing pressurized moisture laden air against the fluid in your m/c and will get unwanted moisture into the fluid. David uses nitrogen to avoid that potential problem because it's perfectly dry and an inert gas.

So how to you use your motive without fluid in the pressure vessel?

i have used them in 12 calipers total over the last 4 years. no issues. it's nice to be able to bleed the brakes with no need for an extra person or any tools aside from a single wrench

Definitely get some Speedbleeders...
I did have some leakage after a track session on my Z06, but what I found out later is that it was some of the break fluid that got on the threads when I installed them.
I cinched them down a bit snugger before the next session and I haven't had a problem since...10 track events later.
I've run them on a 350Z, 2 C6 Corvette's and most recently an Evo 9. All have seen track days and only 1 problem.
