Question: I don't think I am using this machine correctly. It doesn't seem to close when I insert the ice block. Am I doing something wrong? I can't seem to find a video with the specific machine.
Document: There is nothing wrong with product...I just ordered SHAVED instead of CRUSHED !! I didn't pay attention. Did think it is a bit noisy, and when using ice cubes it is a bit temperamental...I had to rearrange cubes.
I used to eat Ice gola in my country. I have been missing that for longtime since I moved. I bought cheap walmart brand ice shaver but did not give real shave to make Ice gola. I think this is close one. Only drawback is that you have to depend upon their small box to freeze Ice. So you have to prepare in advance and obviously you can't use for more than 3-4 people unless you have planned in advance.
I suggest not using cubes, as these seem to make the motor work too hard and you might run the risk of burning it out. It comes with two plastic molds and if you find yourself in need of more than two, the company sells them for a couple bucks. We just keep the already frozen molds in a ziploc bag and keep filling the two molds with water, we also found a tupperware that is the same size as the molds and we have begun using that as well.
I have only had this a couple of days but I have already used it several times. I find freezing already flavored liquids is the best way to go. I have been using lemon aid in the provided cups and can't get enough shaved lemon aid ice! The texture of the ice is perfect. It's going to be great for those hot summer days!
Unless I'm doing something wrong. The top part that  you hold down to run the machine moves around a lot. I feel like I'm holding on to a jack hammer. otherwise I like this machine.
I used to have this cheap hand-shave ice machine I got from local asian market. Though it made good shave ice, my hand got sored after just one cup, and it became too painful to make 3 servings. Since my family has grown bigger and shave ice at most stores cost too much, I decide to find other alternatives on Amazon. Then I found this wonderful electric Shaved ice Machine by Hawaiian Shaved Ice. All the reviews seem promising. So I went ahead and got one.
My wife and I love shaved ice desserts and we've considered purchasing a home machine before. We were hesitant that it wouldn't give the consistency we were looking for. We read the reviews and decided to purchase S900a. WOW! We absolutely love it! Exceeded all expectations. Turns ice into snowy deliciousness! As my wife would say, "can't believe something as simple as shaved ice and condensed milk (her topping of choice) would taste so good!" We use it just about every day.
Also, a tiny sliver of ice isn't shaved into snow and it's left in the machine, but I think it's to protect the machine from the shaving/knife part.Overall, great machine. Don't expect to be able to make a ton, but you can freeze the blocks and store them up in your freezer if you're ever wanting more than 2 shaved ice at a time. Each block only makes 1 shaved ice, but they are a decently big size.
This is a great little gadget. With all the heat in the Midwest in the last few weeks, I found myself thinking, all I want in the world is an orange juice snow cone. This does the job quickly and well. I felt a little ridiculous sitting with a bowl of orange juice and ice. I also felt something close to ecstasy knowing that the next time the need arises, there will be no need to hunt for a street snow cone vendor.This is a terrific thing.
Amazon does sell mini ice trays for alot cheaper (like 5-6 bucks). Mini ice trays vary from 40-90 small ice cubes. Or do the traditional way. A small canvas pouch with something sturdy to crush the ice. I decided to keep it because I don't to have to ship it back and wait for the refund especially using FPO address. I purchased mini trays and use the shaved ice machine for different purpose or give it away.
Answer: You know what? I've only used the ice block a couple of times. We're always in a hurry to have some shaved ice so we use ice cubes (ice maker) from our freezer. We just open the top and throw the ice cubes in there. It works well for us. We love this machine. The quality of the shaved ice is nice. I have learned to put a little empty cub under the opening after we are finished to catch any remainders of melting ice. We don't have to clean it up that way. Hope that helps!
