I just think it wrong to advertise such a thing and not deliver a product to that spec.
They dont say that there binoc's are fully collimated,aligned,centered whatever.... So one would not be able to hold them to that.
But as EdZ posted, he had disected binoc's that claimed to be FMC on the optics and only the objectives were. Poorly,but were.
Thats just wrong.(Not you EdZ,what they did)
And Zhumell's ad state's on there 20x80's that they are FMC optics.

Joey ,
You are absolutely correct to think that .
< They dont say that there binoc's are fully collimated,aligned,centered whatever.... So one would not be able to hold them to that. >
-- good point ! --
--but I suppose it COULD be argued under sales of goods acts that any binoculars NOT correctly aligned cannot serve the purpose they were intended for -- i.e for looking at objects through , using BOTH eyes --
-- preferably the SAME object or objects -- and not , as Bill C so amusingly exaggerated about the other day -- with one side aiming at Texas while the other side is pointing towards London ! :-)

Hi Kenny:
I remember you asking me if I had decided what I wanted to get my master degree in. Well, I was thinking about Technical Communications or Graphic Design. However, I have come to believe—based on need--that there would be a greater future in psychiatry.
Cheers,
Bill

Well, my real philosophy is to pay an extra buck and get something decent. But these things were so cheap that i ordered actually several pairs. Finally, after reading all the valuable information provided by some of the most experienced users here, i decided to cancel the order. Thanks for your really valuable input.

I'm sure there's a typo there, that Bill meant you *don't* have to be accurate -- just believed. It's a shame but unfortunately true to at least a significant extent. It's been true since the time of the Roman Empire at least; they are the ones who said, "Caveat emptor!" Let the buyer beware!

Ovi ,
My personal opinion is that you were wise to do so , and brave to admit doing so on this forum .
That news will gladden a few hearts around here .

I can't think of a single country that wouldn't have a few pawn shops. ATMs could tell you where they are. If you trust your senses you can make your money further.
A few years ago, I noticed a 1907 among the $29.00 plastic paperweights. It's cost was $6.00. I sold it for $250. The person I sold it to sold it to a collector in Japan for $500.
And, YES, I can sleep very well. I told these people what they had BEFORE I bought it. Their response: "We don't have anyway to VERIFY that; so do you want it?
I did.
Cheers,
Bill

So, Ed you presume to moderate my unquestioned journalistic prowess!!!!! BLESS you!!!! That was an important one to screw up. My "Friend" Kenny doesn't correct me on specifics; he just makes fun of me in GENERAL terms! But then, after what nature did to him, I can understand him wanting to share the wealth. 
Cheers, and THANKS, again!

Bill, you are very welcome! I thought about a PM but wanted to emphasize your point and add the "Caveat emptor" saying. ... And just now I remembered what P.T. Barnum said, which was much less diplomatic than what someone else (Abe Lincoln?) said about how much of the time it is possible to fool how many people.

Ed:
Long too late, I have come to realize that the most precious lessons I ever learned came at the hands of those I refused to heed, because I was a young know it all and KNEW it all. Today, as I witness the softness of their wisdom in their hardness with me, I wish I could reach out to them. Yet, it is long to late. All, I can do now is try to give to others what has been given so freely to me.
Thanks again.
Bill

Some of the people I have spoken with lately, understand so little about collimation, I think most of them could do with a collimoscopy . . . 'specially if they're over 50!

To resurrect the original purpose of this thread, I also picked up a pair of these just now. Couldn't resist the price of $69.
So, how are they? In a word, not bad (okay, that's 2 words). Edge correction is surprisingly good IMHO, again considering price. Coatings are okay, not great. The Zhumell web site is very careful not to say anything about the coatings, a philosophy followed by binoculars.com/telescopes.com. Interestingly, opticsplanet.com lists them as FMC. Not mine. Without surgery, I can only say that the outer objective and eyepiece surfaces are coated (bluish tint), but not multi-coated. Venus was definitely haunted (ghosting) when I looked at it this morning. But Comet Holmes was quite pleasant, as were M42 and M51. I couldn't make out much more owing to the late hour when I got out as well as more than my fair share of clouds.
Focusing was smooth enough, while overall construction is typical Far East. The reinforcing bar is weak and tough to lock in place, which caused the binoculars to pivot on the bar somewhat. Barrel alignment appears to be fine, despite the rather sloppy packing job.
But I don't want to be super-critical. Nope, they aren't going to replace my Fujinon 16x70s, but for 69 bucks, they are a decent deal.

These would not appear to be the same as the Barska X-Trail 20x80 that i have (which can be had for ~100$) as these *do* have multicoated objectives/ep (and single coated elsewhere). FWIW, a review of the Barska version of these 20x80 is located here. I have had these now for a year and my opinion has not changed with much further use from the time the review was written. The only modification these required was the addition of a small shim to the objective end of the center bar pivot. Otherwise they have been good performers and a joy to use--particularly so since i modified an old DX-80 alt-az refractor mount with slo-mo's for them.
They are simply a rock on this mount.
As far as "collimation", all i can say is that these have always 1)shown one star image per star and 2)have never given me a headache after extended use. That is about as "collimated" as a binocular needs to be-- for my enjoyment anyway.
Last spring i took a copy of EdZ's coathanger mag chart with me on one of my trips to my fave dark sky site and although i neglected to make any notes (my bad but the exercise was made just to satisfy my own curiosity) i do recall being distinctly *un*dissappointed at the limiting mag they brought in.
So, after a year of regular use I remain quite pleased every time i drag these "doorstops" out to observe with and, for some inexplicable reason, feel no urge to "upgrade"--at all. Point being that binocular observing can be enjoyed at more than one optical quality level. IMHO of course...
