What is Reddit's opinion of Celestron Omni Series 1-1/4 4MM Eyepiece?

From 3.5 billion Reddit comments

You said earlier that a 4mm eyepiece would cost $50 in the US, I've been finding much cheaper prices. How do I know if I'm getting a quality eyepiece? Idk if I'm missing something here.

What do you think of this one?

As usual... thanks a lot for the help!

I was looking at

From what I can gather, the Laser Collimator should work well, but wasn't sure about the 4mm. It looks like it is a Plössl, but I couldn't find any that weren't. What do you think?

UPDATE: I ended up buying the Meade 130, took it out last night, I was able to get views of Mars and Saturn, including the the rings, with separation between the planet and rings as I hoped for. Problem is, it was sooooo tiny, I could barley see it lol. I was using the 9mm eye piece. Clear, crisp little image, but it was hard to look at. Once I centered the vision, and I looked through the eyepiece, I had to wait for it to stop shaking, then look at this tiny little planet, all hunched over because this telescope is much large than I anticipated (looked smaller in pictures, I don't think it's going to be as portable as I imagined). So small that I couldn't even take a good picture with my digital camera on macro mode, which can usually pick up the smallest details, all that showed up in the picture was a few pixels mushed together, not even a sphere. And annoyingly enough, the eyepiece is located at the front of the tube (idk if they are all like this?) So when I am stargazing I gotta stand near the top of this thing and hunch down, back muscles are getting a workout, I start shaking trying to hold this uncomfortable position, I nudge the eyepiece ever so slightly, then the whole thing image starts shaking for another 15 seconds, ughhh so annoying I just wanna sit in my cozy chair and lean forward to look through a hole.

But overall I am pretty happy with being able to see a planet for the first time, in a big city with alot of light pollution. But I'd really like to see it more up close, and clearly. I wanna go back to the store and buy anther eyepiece, so I can have another look tonight, is something like this good for my telescope?

It's a celestron 4mm eyepiece, I can get better views with a 4mm supposedly. A local store near me is selling them for $23, which is doable for me. I don't mind ordering online either, I just don't wanna miss these epic views of Mars that we are going to get in the next few days.

Hi, max theoretical magnification is aperture in mm x 2 = 260x. However 200x is likely the best as excellent seeing conditions are required to push the magnification to the limit of the scope. Focal length is 650mm so 650mm/4mm = 162x.
