Question: Is the top hollow, or is it a solid piece?  Similar models have a hollow top allowing water to enter through the plunger hole & stay inside.
Document: But it keeps coffee warm, looks great doing it and is easy to clean. All in all its a very solid piece of kitchen equipment. It looks good in both modern and traditional decor. Whether or not its worth the price is totally dependent on your budget but I think it is. I had bought a similar product a couple years ago and use it nearly every weekend. The double wall is of minimal use to me to me though.
The pot is very good looking. The top lid has a hole that the press part goes through; this part has a mesh screen that goes down to press the coffee grounds into the bottom (hence the name "French Press"). The pot makes about 3 full 8 ounce cups of coffee. All the parts are solidly built and fit together well.This French Press (like all such models) works as follows.
Next, remove the lid with the filter and plunger and place 4-5 tablespoons into the bottom of the carafe. Then pour hot water (I use aRosewill R-HAP-01 Electric 4 Liter Auto Feed Hot Water Boiler and Warmer Dispenserthat heats water up to 208 degrees) into the carafe, leaving at least 1" of space at the top of the carafe. Place the lid back on the carafe without depressing the plunger and let it sit for at least 5 minutes to brew your coffee.
The whole process takes a minute or so. I also clean the inside of my pot after every use because coffee oils left behind can make the next pot taste slightly off, but you can go a couple of uses before cleaning if necessary. My favorite way to clean a coffee pot is to put a little automatic dishwashing powder (not liquid) in the bottom with a little hot water. I swirl it around the inside of the pot and then lightly sponge it all over the inside of the pot.
The plunger assemblies are incredibly similar in design, and both containers are double-walled and insulated. In addition, both designs are fully dishwasher safe - very, very handy. They both have open-bottom handles, which isn't my preferences because I like the added grip security that I feel with a full loop handle, but they are both comfortable and easy to use. Because they have essentially the same plunger designs, the force required to push the plunger down is similar.
However when taking the press out it seemed to be quite nice. The style is classic, the weight was solid and the manufacturing looked well made. It looked as though you could heat the water up right in it (however you can't).I'm still practicing with the amount of coffee to put in it butso far it makes a good cup of coffee. It's easy to use and the coffee stays hot for quite a while.
The double wall does what it promises to, which is keep the liquid hot. I put about two heaping tablespoons of ground coffee and then add boiling water. I put the top on and turn it to that the opening is closed to keep the heat in. I let it sit for at 5-15 minutes while I get ready for the day. I have tested the water an hour after pouring it in and it is still hot. Another hour and it is warm.
The instructions state to place the lid loosely over the top during steeping, but I prefer to leave the pot open for the five minute wait.After the time has expired, I use a spoon to scoop off the coffee grounds that are at the top -- it seems to produce a cleaner, less cloudy, cup of coffee. Then slowly press down the plunger until resistance from the captured coffee grounds is felt.
The filtering screen is high quality and there are no wrinkles in it, either on the flat part or the curved part that holds the plunger frame. To clean the filtering screen just hold one end in one hand and with your other hand twist the plunger top (the part you can see outside the pot) until the filtering screen screws off the plunger. Wash and reverse the process to put the filtering screen back onto the plunger.
Use a coarse grind - either with an at-home bean grinder or select coarse on the dial of the grinders available in grocery stores that sell whole bean coffee.One rounded tablespoon should be used per four ounce cup of coffee. My first pot was a test run to determine how much water the container held with the grounds in place - the answer is 28 ounces of water, which included leaving the required one inch of head space at the top. So, I used seven measures plus one for the pot.
Answer: Top is hollow...but I wouldn't recommend this product. While I have had no problems with the lid, I get coffee grounds when I pour because the screen isn't functioning properly. I have tried to locate  a new screen but haven't been able to. Amazon doesn't carry it and the generic ones don't fit.
