"the two halves don't align quite right, in my case they are only slightly out, (maybe 1mm). It worked fine on 8mm pipe but I suspect that if it was much more out-of-line it might damage the pipe, as seen in other reviews.
I would recommend checking the alignment of yours before leaving the store.
When working right it produces nice clean bends and is easy to use."
"i wish i had read the reviews before i bought this "tool" as soon as i got it out the box i had bad feelings, it just crimps the pipe all way round, i wanted the rothenberger one but as needed it that day and screwfix only did next day delivery on the rothenberger one i bought this one, complete waste of money which i will now be returning to get the rothenberger one. DO NOT BUY!!!!!"
"Bought this to do some basic bends on 10mm copper pipe. Bender casting actually showed inch markings. Finish poor & did not seem to be well manufactured. Think Screwfix should check what they are actually selling. Ended up by buying a better Tube bender from Screwfix direct competitor superior quality & at a lower price ."
"I purchased this cheap one because I couldn't find my old pipe bender,what a mistake!! possibly the worst tool I've ever used as it was worse than useless. Luckly found my old ones which blow this cheap make out the water. DO NOT WASTE YOUR HARD EARNED MONEY!!"
"A cheap copy of a professional tool that performs almost as good as no tool at all! Don't waste your money on this.
The straight top half is about 2mm offset from the curved bottom half so it fails to wrap around the pipe properly and initial pressure on the handles crushes the pipe between the two offset halfs so the bends end up with a 2mm "seam" all the way round and almost completely blocked internally.
Spend more and get something that has been made properly. Screwfix shouldn't stock this rubbish."
