Question: The instructions are very vague with this. Do you only put 1/2" of water in the pan...or enough to touch the cups? Found conflicting results on google
Document: Excellent egg poacher. The instructions are for people who have used one before. Fill pan about 2/3 full of water, spay cups with cooking spray. For a  soft egg yolk cook six minutes. Water must be boiling to start. It takes 5 minutes for the white to set. Yes I put it in the top rack of the dishwasher.
I've been using a single egg stainless steel poacher for years. However, I really wanted to eat more than 1 egg at breakfast so after reading tons of reviews on different types of poachers, I went with this one. I love it! I spray the cups with butter spray, put water in the bottle, crack my eggs in, season and boom.
I love poached egg but had one of those poachers that went into the microwave. It made great advancements in getting a rubber egg. This type of egg poacher is the only way to go for a truly good poached egg. The cups are large enough for all but the most extreme 'jumbo' egg (I've not found one that big yet). You have to be careful lifting the cups from the steaming water so that you don't burn yourself - wear kitchen gloves or use a pot holder.
For the price the Excelsteel is a well made poacher that works great on our gas range. It's looks nice enough to stay on the countertop and makes perfectly poached eggs.You have to lightly oil the cups per instructions and I sometimes use a mini spatula to edge around the eggs and they drop right out. I also use the spatula pointed handle to move the cup wire extension to the outside of the pan and pick it up using a hot pad.
All you have to do is half fill the pan with water, grease the egg cups and you will see how nice eggs are poached. You have to determine by trail and error the time it takes to cook them. But the results are fantastic. I'm extremely happy with this product and fully recommended. Greetings from Colombia.
I use this egg poacher for 2 or 3 jumbo eggs. The amount of cooking time varies with egg size and number of eggs. Since I use only 2 or 3 eggs at a time, the eggs are done very nicely. The egg cups must be sprayed to easily remove the eggs. I never tried it without the spray. The pan is made of thin stainless steel. The handle does not get hot. The water boils quickly and the eggs are poached within 6 to 7 minutes.
This poacher is very easy to use. You can make one to four eggs at once. Heat water in the pan with the frame on top. Butter the cups. When the water is simmering, drop an egg into each cup and put the cups into the frame.
I really like this egg poacher. I was using those pods that you put in boiling water, but this pan is much easier. Oiling the cups assures that the eggs will slide out easily. I think four minutes makes the perfect egg.
This is so much more clean and neat than putting the eggs right into the water. The pan isn't all that heavy duty but it doesn't need to be. It seems a little more expensive than it should be but I really like how easy it is to use and clean. I always spray the cups before I put the egg in and they slide right out!
I had looked for an egg poacher with the following requirements. 1. Had to have non-stick cups. 2. Had to have individual removeable cups. 3. Had to be able to poach 4 eggs at a time. This egg poacher met all the criteria and was stainless steel too. I am very happy with this egg poacher and would not hesitate to buy from Amazon again.
Answer: I actually put water to just below the cups.  And that seems to do the trick.  I agree the directions are a bit vague, but honestly I think as long as you have water in there your fine.  Make sure it has started to boil before putting the tray in with the eggs.  Took me a while to get the perfect egg, but I had never made them before so it was a bit of a learning curve, but now they come out perfect.  Hope this helps.
