Pros: Cheap, easy to use, portable, comes with attachment for quail or bantam eggs.
Cons: Rather low lumens.
This is a great candler if you are only planning to hatch a few eggs, it is very cheap and handy. It is only 250 lumens, so it doesn't provide too much detail, but it will effectively show veins and air cells, even in blue or green eggs. One plus is it comes with an attachment for quail or bantam eggs, which has come in handy! Overall, I am pleased with it, but I wouldn't mind paying a little more for higher lumens.
