I am not familiar with them but I have never seen a scope that can be reliably adjusted that cost less than 250 bucks and those are few and far between. Bushnell 3200 or the Nikon Buckmaster are the entry level scopes for long range work IMHO.
Don't laugh, but I have a CP 3-9x50mm Adventure Class scope on my springer air rifle
As some of you may know, springers are far more brutal on optics than real firearms due to their 2-way reverse recoil (I've seen many high dollar scopes shatter because of this)
I won the scope in a contest on rimfirecentral a few years ago and it's been holding up just fine
Although my range is limited to 100 yards, I'm still able to make MAJOR click adjustments and it returns to zero perfectly every time
Here's an old field test video I made a while back....
YouTube - Center Point Optics Field Test
Optics are clear (although the eye relief is pretty short) and the locking turrets are solid, however, the illumination is useless (makes the entire tube glow) and the crappy flip cap usually pops out and hits me in the eye every 10 shots or so
That being said, I recommend them highly
Power Class is great (unlike the Ad.Class, they have an etched reticle with no tube glow), but at a higher price...
Adventure Class is fine, but be aware that there was a bad batch of 40mm tubes that made it on the shelves last year that have a problem with running out of elevation adjustment (CP has and will replace if needed)
AR Class is crap (unless you're packing paintball guns)
