I own two Swift Premier scopes. Both were under $200, easily.
A 4.5-14x44 A/O with mil-dot reticle, and a 6-18x44 A/O with mil-dot reticle.
The 4.5 is on a Remington 700 LS .221 Fireball, the 6 is on a Remington 700 VLS .22-250.
My experience with them has been very positive, though I can't speak to their customer service as I have not needed it.
The function is very good. The target turrets are accurate, track well, and click adjustments are positive.
The reticle works exactly as it's supposed to, and the dots are large enough to see very well, without being too large to use in the field. The crosshairs otherwise are a very good medium-fine duplex.
The AO works very well, as does the rear ocular focus ring. Both (on both scopes) seem to be calibrated very closely to the range gradations on the AO, which is nice (for a change).
The clarity is excellent. I'd put it not quite on par with the Leupol VX-II series, but probably equal to the Sightron SII series, or very near to it, and as I rate the SIIs about equal to the Burris FFIIs and Weaver Grand Slams and Nikons (above Buckmaster series), that should tell you where I think they rate.
I can't speak to the durability, as I don't abuse them on the rigs that they are on.
As far as light gathering, this is where I think the Swift falls a bit behind the SIIs, but since the SIIs are phenomenal at that, well...
In field use, the 4.5 was out with me yesterday. I had zero problems using it at 4.5x to hit crows quickly at 125 yards, and the clarity was excellent for watching groundhog #4 at 200 yards, seeing the color shift on his coat as he turned and moved in the sun, and in fact, at 10x (the power the mil-dot is calibrated for), I was easily able to see the grass moving and pick out large weeds (thistles) to wait for him to clear. The weather was excellent, so it wasn't really a test of any inclement or dark conditions, but still, the clarity did impress me greatly.
Also, at 14x, I was able to identify a fox squirrel at a lasered 452 yards as a squirrel and not a small groundhog (what he was doing 100 yards into the field still puzzles me), so that should give you another idea as to the clarity of the Swift scopes.
Anyway, I think the Swift scopes are an excellent value for the money, and I'd not hesitate to buy another (or several) nor to recommend them to someone else.
Hope this helps.
