Question: It says that the strainer is stainless steel, is that the only part that comes in contact with the juice?  Are any parts aluminum?
Document: I got this for my dad for Christmas. He's got a few orange trees growing in our backyard with lots of oranges. He's already squeezed about 10 gallons and put some in the freezer. The package was substandard as it arrived in pieces with only the plastic bag protecting the juicer. There was no damage to the juicer and he says it works great. Not that the juicer needs instructions, but it should come with a parts list and contact information to order parts in case they are needed in the future.
I don't think a simple parts list with contact information is to much to ask to keep in a file for easy access.
Worked pretty good, until the cheesy pot-metal top cone broke. Product Rep at import company says they do not get any replacement parts from the Chinese maker. Can't weld pot-metal, it's going to the landfill.
This citrus juicer is excellent for relatively small amounts of fresh juice. It is very well built. I keep it out and handy for quick use. I wish it had parts that gave a variety of straining for the juice.
When I opened the box I was taken aback by the strong odor (paint? chemical? something else?). I put it in the sink and washed it down with soap and water and then wiped it down with lemon juice. It was only the black stand itself. The chrome-colored parts were fine. After a few days on the counter the odor was completely gone.Gave it 5 stars even with the negative comment because its does such a great job juicing.
This juicer works great! I was so impressed with the commercial juicers that some of the street vendors have in Europe that I had to have one for myself. This juicer is a heavy commercial quality and comes apart easily to clean
This is a high quality citrus juicer that is tons of fun to use outside while making fresh lemonade or mixed drinks. It's sort of like having your own carnival/bar in your backyard. I was very impressed with how heavy-duty it is. The removable parts are easy to wash. I rated it 4 stars instead of 5 because it sits really low and most cups do not fit under it - a little annoying when making lemonade.
Would have given 5 stars except for a few reasons. Number one....the packaging was horrendous! I couldn't believe anyone would send anything that was so broken up and taped up and the item actually came! Second....no info at all or paperwork. Nothing on taking it apart to clean, parts, where it came from. Nothing! Got 2 L shaped wrenches and a washer...for what? The item itself is made very sturdy and juices really good.
Here is a haiku about this juicer:Sometimes you need juice.If all you have is some fruit,It will be made juice.
it is real heavy duty and will make fresh juice for years to come. It is easy to operate and we love it
Answer: The part that presses on the peel as you squeeze is aluminum. But it does not come in contact with the juice
