I have been interested in spiraliser a for a while now. I first saw one at a baking show last year and bought it, but found it incredibly hard to use and gave up. I then saw a table top version in a shop that was giving a demonstration. I tried to use it, but it turns out that it was not suitable for left-handers. I consigned myself to the fact that I just wasn't able to use one. But then I saw a handheld one that came with a money back guarantee if I didn't like it. I bought it, tried it, and love it. I use it so regularly now. The key is finding one that works for you.
No I don't have 1, so I don't know if I'd like 1 or not. It would depend on the price. I bought a footpath about 10yeras ago, because I said to my self I had to have 1, & I'll always use it, & how wonderful it would be to use 1, & I haven't even used it once !
I was very inspired to buy on and saw one on sale in the big supermarket here, in the "burbs" in Melbourne for $8. It was a hand twirler one in green. You could Google the one I mean. I got out the zucchini and carrot to test. The carrot spat out irregular chunks of grated carrot and the effort to turn it with the carrot in was a huge effort and difficult. So I wrestled the carrot out and thought seeing the zucchini was soft then turning etc would be a breeze. It was a disaster! It's hot mangled up and the only thing I saw was the irregular grated zucchini bit's. I returned it. Since then there are heaps to choose from with one costing $69! Most are around $30 it seems which all look the same except one which looks like how you mince things and it has 4 different blades to use and you use a handle but make sure it's got suction thingies on the 4 feet or you might scream. I use a potato peeler but of course it doesn't twirl or spiral. I'm still looking but you have to have strong hands and wrists and patience. :-)
I find this kitchen tool particularly fascinating! Seeing people use it on TV makes it look so easy! So I finally went out and bought one for myself. I tried to make zucchini spaghetti and failed miserably! Not sure what I was doing wrong but it just didn't work!
I have never had a problem with courgette, but other vegetables - sweet potatoes in particular - do require a lot of muscle put into it. It can also depend on the spiraliser; I went through three before finding one I could use.
Are you left handed? I am and that is one of the reasons I had difficulty with some models.
