I fairly recently had one of these new light grey "RCBS 10/10's" across my desk. Did it work? Yes, not too bad. However, I really don't think these actually have anything to do with RCBS or Ohaus at all. Don't confuse these the Genuine Chinese made RCBS 10/10's that have been available for the last 8-10 years or so.
As you all may know, around 10 years ago RCBS/Ohaus moved their reloading scale manufacturing from USA to China and Mexico, I believe at that time they quietly dropped the 502 scale and continued with only the 505 and 10/10 scales. Most of these RCBS Chinese made scales worked well enough, some were just about Ok and some were real dogs. All these scales are cast in the base "Made by Ohaus, USA", many also have a small paper sticker in the base saying made in China. Many people are unaware their scale is made in China and assume because of the inscription in the base that it is a USA made scale. The only way to tell is if you have the original box where it actually states where it was manufactured.
Around 4 years ago RCBS suddenly dropped the 10/10 and the 505 from their catalogue, ( I believe because of the QC flack they were taking) and introduced the RCBS M500 and M1000 scales, again made in China. Whether these new scales have any connection with Ohaus I have no idea - they do have the same knife edge/floating agate bearing system but as these are now out of patent date I don't think that is any indication, they are certainly not marked on the base in any way. On the whole, I have found the M500's to work well and to be of a consistently higher quality than the Chinese produced 505 and 10/10's.
My feeling is, and it's only a guess, that these new RCBS 10/10 scales being offered are made in the same Chinese factory that had the contract/licence to produce the genuine Chinese RCBS 10/10's.. When RCBS pulled the plug and chose another manufacturer to produce the new M500/M1000 scales the original factory was left with a lot of unfinished stock and also the tooling to make the 10/10's and this is whats being sold now through Amazon.
If this is the case, I can't imagine that the QC would be better than when under the RCBS banner and probably not so good. If you took a gamble and got a good one I think you would be happy - if it was a dog it would only be fit for the bin.
