I used these OLBRUS legs to build a custom desk for my sewing room. The metal is thick and heavy-duty, which is exactly what I needed for my heavy industrial machine. It doesn't wobble at all when I'm working, which was my biggest worry. I've tried cheaper legs from IKEA and Amazon before, but these are on a whole different level

It's okay, I guess. I didn't notice a massive difference from the OEM fluid I used last time, but the price point is definitely better. My mechanic said Idemitsu actually makes the stuff for Nissan anyway, so it's probably fine. Just wish the bottle had a better spout for pouring.

They are okay. The quality is definitely there and the material feels premium, but I'm not sure if they are $80 better than my usual brand. The fit is a bit weird in the thighs for me. Might keep them, might return, idk yet.

As someone following a keto diet, finding snacks that actually satisfy a salty craving without ruining my macros is tough. These roasted edamame beans are a game changer; they have a very clean ingredient list and the nutritional profile is impressive—lots of fiber and protein. I usually keep a bag in my desk drawer at work to prevent me from hitting the vending machine. Highly recommend the sea salt flavor if you want something simple.

This is a high-quality product for the price point. Holistic Depot seems to have sourced this ethically, which is important to me. The 4 oz bag is quite large and will last a long time since you only need a few flowers per cup to achieve that deep indigo hue. My only minor gripe is the resealable bag is a bit finicky to close, but the tea itself is excellent.

They're okay. The cushion is nice at first but it flattens out pretty fast if you're on your feet all day. Better than nothing though.

The dealership wanted like $150 to fix my mirror on my 2019 Sportage which is insane. Bought this SKOUIO glass instead and it honestly works great. The fit is almost perfect, though I did use a bit of extra super glue just to be safe because the adhesive pads it came with felt a little weak. For twenty bucks though you really can't beat it. Saved me a ton of money.

i really wanted to like these because of the price but they just didnt work for my fountain model even though it said it would. the water flow got really weak after only 3 days and I had to take it all apart to fix it. also there was a lot of black charcoal dust in the bottom of the bowl even after I rinsed it like the instructions said. going back to the more expensive ones unfortunately.
