Not a bad first juicer
I bought mine in December 2007. Shortly after the warranty expired, one of the retaining straps failed. I managed to fix it myself, although, it does not hold the lid on as tight as it did when new. I contacted Hamilton Beach and all they offered was to sell me a brand new one since this was out of warranty. I can't imagine why a single strap cannot be replaced - it's a separate part and easily comes out. Up to this point, I only used it once per week so needless to say, I was disappointed with the quality.
I decided to get into juicing for the health aspect. This is my first juicer so I will just tell you what I liked and disliked. You cannot put in large whole fruits. In fact, the average sized apple or tomato was easily lodged in the mouth. I always cut up my fruits/veges so it's really not an issue - but is misleading. Not sure if it's because of the broken strap, but the top leaks for high liquid items such as tomatoes or grapes. It can make a real mess. The motor is strong but does "bog" down when you need to push an item through. Whole apples are particularly difficult but nothing major. Overall, it juices and I like it. I think my greatest dissatisfaction is the broken strap. If it weren't for that, I think I'd give it a 4 or 4.5.

A balanced review
I really like my Hamilton Beach Big Mouth Pro Juice Extractor but I think it is important to see the big picture.

I like that it is relatively easy to clean so that I can use it frequently. But it is really best for juicing hard fruits and veggies. It is great for celery, radishes, carrots, and apples, for instance.

It is not good for oranges, grapefruits. Those fruits just seem to go directly into the pulp container so it is a waste. For those juices I use a citrus juicer. If I want to mix citrus juices into my veggie juice I use both machines.

If you want to add banana you are going to need to use a blender. Is there a product out there that does it all? I don't know.

You don't really get a clear juice, you get more of a julius with some pulp. This doesn't concern me. I like mixing fruits and veggies together for juice.

Like others recommend I put a little plastic bag in the pulp container to make cleanup faster.

I really love the taste of fresh juice so I don't mind playing with a few electronic appliances. I appreciate the ability to add more fruits and veggies to my diet and I've started eating more fruit (non-juiced) as a part of my diet so that is a nice outcome.

pretty good
It's pretty good. We've had it for a few months now. It's still working great and is easy to clean. Its just a nuisance to clean it every time. Its been used almost daily with no problems, so its fairly durable. My mom's happy with it.

SO MUCH WASTED
I orderd this produt because of the great reviews I read. BIG MISTAKE. You need to put alot of fruits/vegetables in to get one small glass. ALOT OF IT GETS UNUSED. This machine wastes so much. More pulp than juice. Next time I think I am going to by the VITAMIX. I looked at the prices on them and they are very expensive but I guess I will have to save up because I think it is more what I am looking for. I want a blender type where you can throw everthing in and get a whole glass. This way you know the quantity you are putting in is the same you get out!!!

Good for weekly juicers, not for "hardcore" juicers
Bought this at a store. For the first few weeks, it worked good. It's loud and it's little feet kept falling off but a little glue kept the feet in place and yelling "JUICING" got my fiance used to having his shows and/or phone conversations interrupted. Within a few weeks I was digging into the "pulp" collector and rejuicing. A few weeks later the juice was leaking all over the counter and the clasps were cracked at the joints. I'm a 120lb 5'5 female who was easy on this...and it crumbled in about 2 months. It's at the dump...I didn't bother with the warranty because I don't want to deal with all of that mess again.
If you are a light juicer- may be a good buy. If you are more of a daily/several times a day juicer- don't buy or you'll be back on the market in no time.
