Love this product

Absolutely love this product. It has worked every time in any time I’ve ever used it. I feel like it just gets better as it ages. WD-40 been around a long time and it’s still the best thing for squeaks.

Yes, I recommend this product.

It doesn’t get much more ubiquitous than this bad boy. Squeaky thing? Unsqueak. Stuck thing? Unstuck. Greasy surface? Ungreased. Wide spray or precise dripping, the smart straw has you covered.

Yes, I recommend this product.

Smart Straw Needs Improving, but Good

2 months ago

This product works well, but Smart Straw needs to be improved. A regular nozzle with small and medium straws that you could manually attach would be better.

Yes, I recommend this product.
