Battery lasts and has been able to find small leaks that I missed using bubbles. Compact design and reliable unit. Very happy with my purchase.

Not a good experience, I order a new item, and i was sent a used one, I requested a refund, because I specifically ordered a new one, and now i have to wait at least 2 weeks to get my money back so im without a tool that i need for work for at least a month, until i get my money vack to buy it again somewhere else

The one I received looks very different from what is shown in the pictures. It does not perform as well as I had hoped and struggles to detect leaks that I can find with bubbles. Definitely not worth the money.
