I almost never observe without them in my 9.25. I've loved them since day 1.

And you don't have to squint anymore when you view a planet or a star or anything?

Observing with a binoviewer is rather relaxing. Squinting one eye closed while observing the traditional way is more of an effort/distraction than one might realize.
The fake 3D effect is pretty mild, but on certain objects (M27, many globulars) it doesn't take much of a leap of imagination to see depth in the field.
A very real con can be the weight of all the pieces involved. My binoviewer, eyepieces, and FOCUSER all fell off my Mak Newt a few years ago, but fortunately (?) landed in soft dirt. Even with focusers that can handle the weight without falling off (as most can, I'd imagine) there still is a chance for a lot of sag as the equipment.

Ah I've never thought of the weight issue, thanks for reminding me.
What did you do to get passed it after you picked them up from the dirt?

The focuser was held to its base by a small inadequate set screw. It was replaced the next day with superior hardware and now the focuser couldn't be pulled off by a gorilla.
Regarding other considerations for binoviewers: Certain eyepieces work better than others for binoviewing. Back in the day when I was "working in the industry" I had an opportunity to test most of the big name eyepieces in my binoviewer. The result (at least for me)? Cheap, generic brand X plossls worked best. But there are plenty of new eyepieces out there I haven't tried that I'm sure would work very well. Big forums like Cloudy Nights are very helpful - let everyone else do the testing for you!

Advantages: The 3D effect, viewing comfort, getting lost in the image. I haven't been viewing without them!
The disadvantages (albeit minor):
Weight (most likely will need counterweights), Cost
Fiddle factor (with multiple viewers, far more adjustment goes on (diopter, individual EP focus, etc). Alignment - more difficult to center stars when aligning scope - gets easier with experience.

I would have to put the comfort factor high on the list, I find that if I am looking at an object with a single EP for some time my eyes become very tired, using the binoviewer allows the luxury of longer viewing.
Just my opinion.

A obvious con: Buying twice as many eyepieces, though this can be mitigated if one buys one of the multipliers.

I have to agree that comfort (relaxing viewing) is at or near the top of the "pros" list. That, along with the "wow factor" as you seem to see more even with the same scope at the same magnification.

Hey Randy my scope is 450mm orion tapletop scope with a GOOD/AWESOME set of binoviewers X2 X cel 5mm plossle will I be able to see saturn rings? or the bens of jupiter?

no doubt. You shouldn't need even that much magnification to see those objects. Binoviewers seem to work better at lower magnifications (in my eyes at least). 5mm EPs are going to have VERY little eye relief and require VERY precise positioning of your eyes to properly merge the images.

So what eyepeices do you reccomend?

What did you say your scope was? What diameter aperture? I suspect this is a 114/450 newt.
Choices of eyepieces for magnification are somewhat dependant on scope type and aperture. Unless you can state what optical multiplier you will be using in this scope, it's difficult to discuss eyepieces. But if my assumptions are correct, I would not push this newt to smaller than a 1mm exit pupil.
A standard binoviewer used in a newt with optical attachment is going to multiply by about 2.5x. Is that how you will use this BV? If so, your 450mmF becomes about 1100F. If that's the case I would suggest maybe a 25mm, 16mm and 12mm.

Pros: the view that everyone keeps mentioning
Cons: balancing your scope with the additional weight of a binoviewer and a pair of say 19mm Panoptics
