I think Tasco's quality is low, and their customer service is poor, from my limited experience.
I was given a Tasco ProPoint 3 for Xmas in 1998, that was supposed to fit a "Weaver style" mount on my S&W 686 revolver.
The rings provided were _junk_. Horrible machining of the holes and threads. Overly light, weak aluminum. One hole had almost no threads whatsoever. The rings didn't mate well. They also didn't fit the ProPoint very well, when wrapped around the sight, you could barely get the allen screws to "catch". And they mounted 1 cm off center on the "purchased from Weaver" mount!
When I called Tasco Customer Service, they were "well aware" of these problems, and were willing to send me another set of garbage rings for free, but their comment about the off center mounting was that they hear about it all the time, but usually if you buy a _Tasco_ weaver style mount it helps! Oh, thanks a lot.
Then the weeks started to go by, while I waited for the replacement rings. When calling to check on my parts, they admitted that they have "no idea when my parts might ship", that Tasco is a huge company, and everything ships when it can. That my "replacement for new defective parts" is in a huge queue of all of Tasco shipments, broken cameras, repaired binoculars, salesmen samples for new products, etc.
I wisely gave up on Tasco Customer Service and bought some very nice Millet rings from a mail order house. Beautifully made, solid, snug, and they fit centered on the Weaver mount.
Three months after I notified Tasco about the defective rings, I did finally receive another set, which were almost as bad as the ones I could not use (they did had some threads in every hole). I surmise these rings are being made in China, by the way. I never seen metal items made this badly, except from China.
And the rst of the sight seems poorly machined, as well. It works fine, but all the threads are sharp and rough. It is difficult to get the battery cover back on for this reason, for example. It doesn't seem sturdily made in any respect.
My only experience, but after talking to the folks on the phone, I don't think it is unusual.
