Lab Micropipette, Adjustable Volume Single Channel Pipettors,100-1000ul…

This product is highly accurate, reliable, and overall good quality for even at-home chemistry. I have confirmed that it does indeed deliver exactly the amount of reagent you select by using my ultra-precise scale. I have no worries about the effectiveness of this product.

Works well!

UPDATE: Company reached out and offered me a refund even though it was outside of the return window. Lack of good customer service is what's wrong with most businesses today. This one does not fall short in this area and for that reason I've changed my rating. Thank you. Disappointed that it didn't come with any tips to start. I didn't realize this until I got ready to use it and then I had trouble finding anything small enough that didn't cost 5x what the unti itself cost. I had it too long to return once I got around to using it or I would've sent it back. Poor value for my money.

I'm completely blind, so working with small measurements can be challenging. I bought this micropipette hoping it would help, and so far, it's been great. I don't fully understand the number scale, since it starts at 1; so when the screen says 100, I'm not exactly sure what that translates to. Fortunately, I don't need super precise measurements, so trial and error worked well for me. Now I know which numbers give me the results I need. But this could be confusing for someone who needs more exact dosing. Adjusting the numbers was tricky at first without vision. The first time, I had help from Gemini with streaming of video, waching the micropipette with the phone camera. I counted how many steps there are per turn, so now it's easy for me to set the amount I want.

Good quality , you get value for your money.
