Hello,
I am new (about 2 years) to photography (as a hobby) and have been enjoying it so much (family, travel, city street etc). My question to you is: I just ordered an Optodio macro 8-in-1 52mm Kit: reverse ring, close-up lenses and metal extension tube all for about $30. Then, I read about the macro Tamron lens 90 mm 2.8 which is a lot more expensive than the tubes. Did I screw up by ordering tubes and these close up filter-like lenses (I am sure you guys know what I am talking about)? What I read does not really go into a lot of details about these tubes but they must work, right?
I am trying my best to have a reasonable gear for a big trip coming up (the camera is Nikon D5300 and I have about 6 lenses, speed light and a good tripod) and the only missing thing was the macro equipment, which I am really enjoying. No place to try these things in person anymore, it is all the internet and you guys.. Help! Thank you
Eric

Those $30 (and and other similar or even cheaper) macro extension tubes do not have either electronic nor the "screw drive" connectivity, so your autofocus lenses will be manual focus only. That's usually okay, because a lot of the time it's easier to do macro work with manual focus, anyway.
But, much worse, with those "cheapies" there also will be no means of adjusting the lens aperture on any lens that relies upon electronic aperture control (such as Nikkor "G"). If you have a lens with a mechanical aperture control, i.e. it's set with a ring on the lens itself, that will be fine. But with any "G" or "gelded" lenses you will only be able to use the aperture wide open, which makes for extremely shallow depth of field at close focusing distances.
I would have recommended spending a little more for the type of extension tubes that have the electronic contacts for aperture control of all lenses... such as these:
https://www.amazon.com/dp/B00NVRCDYU?psc=1Personally I use the Kenko tube set, which also fully support AF and aperture control, and are higher quality materials and better design:

Macro extension tubes are very versatile and handy to have. I've always made a point of having a set in my camera bag, since learning to use them some 25 or 30 years ago. They can be used with many different lenses to make them closer focusing.
Even though they're versatile, you have to practice with and learn what they can do with different lenses and the extension tubes have their limitations... In most cases you're forcing a lens to focus closer than it's designed to do, which can compromise image quality to some extent (depends upon the specific lens, distance and aperture used). The longer the lens focal length, the more extension that's needed to have a significant increase in magnification. As an example of how they can effect images, this was done with a 25mm extension tube on a 50mm "normal" lens...
In the above image there's a lot of vignetting and softness in the corners, caused by making a lens focus far closer than it's intended. This isn't necessarily a bad thing, though. I used it deliberately for the above.
A true macro lens will generally make for better image quality, plus will usually be faster and more convenient to work with. It also might offer higher magnification than possible with a non-macro lenses plus extension tubes.
You mention the Tamron SP 90mm f2.8 macro lens and that's a good one with a long, long history. I use a manual focus Tamron 90mm from the 1980s and it still works great...
The older version of the Tamron used for the above has 1:2 max magnification (half life size, which allows it to be quite compact), unless an extension is added. I used it combined with a 25mm extension tube for the above shot. The aperture on this old lens is manually adjusted, too, and in this case was set at f11 to increase depth of field (can be used in Manual or Aperture Priority auto exposure... not in Program or Shutter Priority AE). That makes setup a little slower and causes a pretty dim viewfinder and capturing a shot of a quick, moving subject can be pretty challenging.
That old 90mm Tamron cost me all of $20 at a local second hand store. To to use it on my Canon cameras I had to spend another $40 to get an Adaptall2 mount for it from China.(This vintage lens is part of a series designed to use easily interchanged mounts and to be adaptable to almost any brand of SLR/DSLR... Personally I also have Adaptall2 to fit Canon FD, Nikon F, Konica AR and Pentax K/AR vintage cameras.) Over they years I've used several of the Tamron 90mm and knew they were excellent. So when I saw one in very good condition for very little money, I jumped on it! It's not as fast and convenient to use as some more modern AF capable macro lenses I use, but the image quality is fine.
The modern Tamron SP 90mm macro lens is full 1:1 and actually comes in two varieties, both with autofocus and aperture control. There's a cheaper version that isn't internal focusing and doesn't have image stabiliztion (which is okay, since it's not very effective at high magnifications anyway). The other Tamron 90mm is internal focusing (doesn't increase in length when focused closer), has higher performance USD focus drive and a Focus Limiter, as well as VC (vibration control) stabilization. Both are full frame capable lenses (FX), so are usable on both FX and DX cameras.
Tamron also makes a compact SP 60mm f2.0 Macro lens (DX). I use one of these and it's bigger than usual aperture makes it double better than most macro as a portrait lens. Like the cheaper 90mm, it uses a lower performance auto focus drive that's fine for macro and portraits, but not fast enough for sports or other action shooting. The Tammy 60mm is internal focusing and quite compact, but is "crop only" (which would be fine on your camera).
Yet another Tamron macro currently available is an SP 180mm. Also a fine lens that gives more working space, but is considerably larger and a lot more difficult to use handheld.
There actually are a lot of very good macro lenses.
Tokina 100mm f2.8 AT-X is one of the least expensive. One problem is that it's an AF-D type lens, so won't be able to autofocus on a D5300 camera.
Sigma makes several macros: 50mm f2.8 (compact), 105mm f2.8 OS USD, 150mm f2.8 OS USD, and 180mm f2.8 OS USD. All these will autofocus on your camera and are "DG", which means they can be used on FX cameras, as well as a DX model like yours.
Nikon themselves offer several excellent macro (they call them "Micro"). "AF-S" type that can autofocus on your camera include: 40mm f2.8 DX, 60mm f2.8 DX, 85mm f3.5 DX and 105mm f2.8 IF VR FX. Once again, manual focus is often fine for macro work, so you might also consider AF-D type or even vintage Nikkors, which can be excellent lenses.
For most people, I recommend the moderate focal lengths... 90mm to 105mm is a good compromise of working distance, hand-holdability and versatility for general macro shooting purposes. 50mm to 85mm macro lenses are more compact, but put you a lot closer to your subjects at the highest magnifications.... may be fine for indoor tabletop studio work, but can be too close for shy critters or those that sting or bite! Typically a 35mm, 40mm or 50mm macro will have roughly 6" or less minimum focus distance (MFD). 60mm will have about 9", while 90/100/105mm will have about "12, and a 180mm lens makes for about 18" minimum focus distance (MFD). Keep in mind that MFD is measured from the film/sensor plane of the camera... so some of the distance is occupied partially by the camera and the lens itself, as well as any attachments to the front of the lens (hoods, macro flash) or any extension tubes installed behind it to increase magnification.
Have fun experimenting with macro.
