ONiLAB Lab Micropipette, Adjustable Volume Single Channel Pipettes, 10-100 Ul

I've been using the ONiLAB Lab Micropipette for a while now, and it's certainly durable – it's lasted a long time without breaking down. However, despite its longevity, I don't believe it's worth the investment due to some significant design flaws. My biggest issue is that liquid can easily get inside the pipette's mechanism, even when being extra careful. This makes it incredibly difficult to clean thoroughly. The prospect of disassembling it for a proper clean is also problematic; based on my experience with similar devices, doing so often compromises its future functionality, or worse, risks parts coming off entirely. For dispensing raw materials, I'd honestly recommend sticking with simple, inexpensive plastic or glass pipettes. While they might be single-use for each material, they eliminate the cross-contamination risk and the headache of trying to clean a complex, flawed instrument like this. The convenience and reliability of basic pipettes far outweigh the perceived benefits (and actual frustrations) of this micropipette.
