Just a heads up, these are a pain in the ass to clean. We went through two before realizing that we don't really need to "spray" our oil...using a brush works just fine.

This 500 milliliter glass oil sprayer is mainly appealing for its low promo price and handy kitchen use, especially for air fryer cooking and other light spraying tasks. The glass bottle is a plus, and the black version is the one that has repeatedly worked with the clipped coupon and page coupon. Cleaning is the biggest drawback, with repeated reports that it is hard to wash out, though vinegar and a dishwasher rinse can help. There are also notes that the thumb latch can misfire at first and that the glass can break if dropped, making it a cheap but somewhat finicky kitchen tool.

Common Questions (5)

  • The coupon and clipped listing discount work on the black version, while the gray and white versions reportedly do not qualify. Switching to black is the practical fix to get the deal price.

    dukebabylonskyline7349Metalbender01LimJahey

  • Prices reported range from about $5.33 shipped to about $8.55 after tax, depending on the base price and whether both the promo code and clipped coupon apply. One checkout showed a $12.99 base price with a promo and 10% coupon bringing the total to $5.33 before tax.

    Guy767Metalbender01dolittlemoore

  • Yes, it can be a pain to clean, and some owners ended up replacing or discarding it because of that. A workable cleaning method is to spray vinegar through it, rinse with water, and then run it through the dishwasher.

    MikePDKracker509hamarabajaj

  • It can spray well enough for air-fryer use and for general oil application, but early use may trigger the thumb latch and send oil onto nearby surfaces. Another concern is that some similar sprayers mostly squirt oil instead of misting it.

    tphdCoolStew3336zephyrprime

  • The glass bottle is a plus for durability and feel, and one owner described this model as having very good quality. The downside is that glass can break if dropped, so it is less forgiving than plastic.

The product, coupon, and link are all of Amazon. You have to apply the coupon at the checkout screen/page.

Change the selection to the black model, if you are lucky to get it there is a coupon that appears on page, be sure to get that also. I paid 8.75 after tax.

i have one of these and its nice but the first 3-4 times you you it will pull the thumb latch expecting it to open up the pouring door. Instead you will shoot EVOO over a random kitchen surface. annoying

Seems like the base price has decreased to $12.99? I was able to buy it around $5 shipped after applying the promocode and the 10% off coupon in the listing; thanks OP.

The AI generated photos in the product's description does not inspire me with confidence though. That's usually a good indicator of poor quality cheaply produced crap that some funky "company" slaps their name on and tries to claim it as their own.

I probably could purchase this in bulk via a Chinese based website like Aliexpress, slap a logo on the product like "Cheap Basterd's Best" and try to sell it for a profit as well. Still for around $5 shipped, I guess I'm getting a fair deal...

I will give it a shot. I dont spray oil, but I will use it for vinegar for vegetable / fruit rinsing. Hope viscosity difference wont be an issue but it is so cheap that it is w/e. Thanks OP.
