What is Reddit's opinion of SVBONY Telescopes Eyepieces 1.25 inches Eyepiece 68 Degree Ultra Wide Angle Telescope Accessory 9mm Focal Length Multi Coated Astronomy Gifts?

Also do you think this piece will do to? eBay says it’ll take almost a month for that 9mm to come but I found a SVBONY on amazon for 39$

SVBONY Telescopes Eyepieces 1.25" Eyepiece 68 Degree Ultra Wide Angle (9mm) https://www.amazon.com/dp/B07C6HDR58/ref=cm_sw_r_cp_api_i_natkCbJS6XBBW

It is a fine zoom eyepiece. Svbony sells budget equipment so it is not the best, but will get the job done.

Imo, I think it makes more sense to just buy a few separate eyepieces. The main issue with zooms is that at the longer focal lengths the FOV is smaller. In this case only 40° (which is pretty small). There are budget eyepieces ($25-$35 each) that have a 68° FOV. This difference is kind of like looking through a porthole vs looking through a window.

It will technically work with a barlow. BUT, this depends on your scope. Most of the time a barlow is not needed. You can get by with 3 eyepieces and imo have a complete set with only 5 eyepieces. A barlow does not have to be one of these. But again, this depends on your scope.

Luckily there are a lot of options of eyepieces to add to your setup. They range in price from about $30 to several hundred.

Once you set a budget we can recommend some specific ones. Imo you can get away with 3 EPs, but you can get a full range of useful magnifications with only 5 EPs.

Some good options would be a 40mm and/or 32mm plossl. These Starguiders are very good for the price, and these 68° “redlines” aren’t half bad either.
