"I have had this for a couple of weeks now and used it every other day. Although the poor little machine has a lot of work to do (!!) it is defintely working and I hope if used for a while longer this will show good results."

"Early days and I'm a natural sceptic about such things. But it does produce a very interesting sensation and I have the impression that it might actually work! You have to put up with a rather uncomfortable feeling - but it's only for a minute so perfectly OK."

"I thought I'd give this a go but didn't hold out too much hope for a quick result. I was amazed that the first time I used it I noticed a difference and after a couple of week's use I am very pleased with it. Having lost two and a half stone quite quickly my chin needed help!! I shall be using this lots as it does work."

"A great and easy item to use."

"This product is very easy to use, is portable so you can put it in your bag if you are going away for a romantic weekend, looks good and 'does what it says on the box'!. I bought this as a 'joke' pressie for my friend who is very vain and always doing neck toning with his hands. We tried it out after christmas dinner and, after the intial laughter (it does tickle a bit to start) we all got really into it and as you are using the Rio you can feel the muscles tighten. I saw my friend after 2 weeks and he told be that he was using it every day and, though it pains me to say, he did look better!!! His jaw line was much more refined! I would recommened the Rio to anyone wanting to maintain a youthful profile or define their jaw line."

"My two daughters and I had one if these for Christmas, it is a bit early to coment on whether they have worked but up to now (January) they seem ok!"

"I bought this elsewhere but have to say I am very impressed with it. You can actually feel the muscles tightening and you can notice a difference BUT you must use it regularly. Once a day minimum to really see a difference in a week"

"Very easy to use, can do it whilst running your bath. Lots of different settings, and I think it could be working but will need a bit longer (hence the four stars) - does buzz on the fillings though so dont switch up high immediately or it will make you jump!!"

"I just got this and i already love it! I truly recomend it to all women but specially for those with double chin like i do! This is gold..i can feel how it tightens my muscles in my neck and the fat seems to gradually dissapear. I will definitely use this religiously! Thank you"

"Had one of these for my birthday and didn't know what to expect - but was amazed. Love using it and can actually see a big difference already."

"Not sure what it's doing for my neck, but it's quite pleasant and relaxing to use."

"This is the best buy I've ever made. It works great and you notice the difference after a couple of times. Maybe if you have a lot of fat it wouldn't work as well!"

"Although easy to use, one is not sure where or how strongly you need to apply the toner. Also could easily make one side lobsided if you don't know how long or where you need to tone. Would have been good to have a 60 second cut off if it is important. Not sure if it is..."

"I have used it every day for the past week and so far so good. I can definately see and feel a difference in the tone of my neck muscles."

"This product works quite well. You can see and feel a difference if you use the product regulary, you will notice good results. The product is good value for money and works quite well. Also an attractive well made design as well. Would recommend this product."

"Excellent product, a must try item before entering down the painfull roads of surgery. I have used it for 2 weeks now and people are noticing theres something different about the way I look, but dont know what !!!"

"This is a very useful little piece of equipment for toning the chin. The area is beginning to feel more taut."

"Well it does seem to be working, I have definately toned up the area around my neck - only a couple of minutes a day - anyone could spare that time. I must admit I was a bit sceptical at first but now have to admit that it has worked for me."

"This is fantastic product, after just 3 days of using it I could see the difference,I would recommend this to anyone who is trying to tone loose skin under the chin or has a double chin."
