Siphon Manual Hand Liquid Transfer Pump for Light Oils, Kerosene, or Water Based Chemicals 2 Pcs

Totally unusable.Unfortunately I hadn't gotten to the project I needed to use this for until today and the return window closed about 10 days ago. This has a hard plastic bulb that cannot squeeze down properly to be useable. It's a waste of money and won't suction up anything.I'm hoping maybe to find a bulb I can use otherwise I'll probably just toss it into the trash. As usual, buying things on Amazon is a crap shoot and if it's made in China, which this is and where they have no quality control, expect it to break, malfunction or just not work from the jump.Wish I could at least get some future credit for this, but since that probably won't happen, it just means I'm ordering less and less from Amazon. They don't seem to care what they sell either as long as they're making money from it.

Purchased these to transfer water from rain barrels. Unable to use as not enough suction. Returned to my previous brand (less expensive) which had been out of stock. The Tezam siphon will work on small amounts such as mower gas tank so keeping them to use for that.

Used for k1 fueling, I had to buy from another manufacture before they even was a week old. because of the leaks.

They were inexpensive and are what I expected. Adjusting the red cap is needed to ensure they work at all. Have not tried other than for adding/removing water from my aquarium - not great for that use. The will syphon OK but were far from drip free.

Will take a long time with this hand pump if are pumping a lot. will work fine for small amounts. Battery operated pumps are better.

Bought for bulk coolant and DEF. Good suction. Bulb is removable for cleaning. Not good to leave fluids in bulb.

My husband wanted this and was happy when it came. He uses it and likes it very much. works fine.

Can't tell if I like or dislike didn't send enough parts to even see if it works
