This one is solid and feels premium with a bit of tuning but really heavy at 8 oz . However I feel like this is one of the best trainers on Amazon from my experience . Sturdy and good overall trainer. Runs for 17$ usd

This one is lighter and has good handles . I’ve ordered it but still waiting on it to come . I’ve heard good reviews as the best amazon trainer . Look up the reviews online or on YouTube but I can’t say much since I don’t have it yet different colors so just look around recommended or look up the color itself . About 26 $ usd

Do not get that one trust me My friend had that one and he let me use it, the play is awful and it pinches you. Also the comb part isn’t even a good comb and it falls apart after a couple weeks. If you want a cheap trainer I would recommend spending at least $10. here is a better option:
This is the one I personally own, it has its flaws but it has outlasted all three of my friends $5-10 trainers. It also comes with a carrying pouch replacement screws and a Screw driver for them. But keep in mind that the wrench feature on the blade is to small to work but the bottle opener works great.
