I did debate with myself whether I wanted to give it four or five stars - it's probably inbetween - but I lean towards five because it has really benefited my lazy life style, and does a couple of cool things not stated on the tin.

I brought it because a male friend body builder recommended it. I wanted a better tummy, and in my karate class I never seemed as hardcore with the ab exercises as my friends, no matter how hard I tried. Worst of all was the dreaded V-sit, which I simply could not do. Using the Slendertone on and off for a week I found it worked those tricky lower tummy muscles, and gave me just that little extra support I needed to master the exercise well enough to benefit from it without the belt.

Basically, it works by emitting an electrical charge into your abs that makes them tense. It does bite a little, but if you're one of those that need to see and FEEL like something's happening - you'll love it. Biggest advice is to not go too crazy with it too soon, however tempting it seems to wap it up to the next level you only end up writing off your ability to move for a week. Same if you haven't used it for a while... as I found out the painful way, just because you could handle level 9 three weeks ago doesn't mean you still can after a period of vegetation.

It works best if you're upright, with good posture, but I frequently use it while pottering around or on the occasional jog. The best thing about this product is that if you've laxed with your training, it maintains a reasonable level of tonage.

4.0 out of 5 stars Works if you're realistic with diet aswell 15 Jan 2008
Verified Purchase
I am so sick of people moaning that this product doesn't work (whilst they sit there eating pizza, and cream cakes and watching TV!!). If you have alot of body fat on your tummy, this definately won't work simply beacuse even though the muscles are toning, there is so much fat that you won't be able to see them!! The best way to acheive flat abs is to have a healthy, calorie controlled diet/lifestyle and use this product to compliment your fitness program. I put on about 5 stone whilst pregnant (yikes!!) and once I'd given birth was horrified by my appearance. I set about losing it through healthy eating- lots of fruit, veg and low fat food and after alot of hard work and exercise, I lost the all of the weight. However, despite regular sit ups, my tum was not as toned as I would have liked so I purchased the belt. I am very very pleased with the results, however, it must be in conjunction with a healthy diet and you must use it regularly. A bit like the gym, I found that it only works if you use it at least 3 times a week. Having said all that, I have now acheived a moderate "4 pack" on my tummy which for me, after having a 9lb baby is nothing short of a miracle!!! Definately recommend this product but you must also pay attention to your diet too.

5.0 out of 5 stars Top Product 23 Aug 2006
These belts are amazing, my partner and I both have one. We are extremely impressed with the results.

I must stress that that they will only work in conjuction with following a good diet and a reasonably fit lifestyle. I am a 38 year old mother of 2 and I have achieved the flat stomach I have always wanted and have only been using it since April.

Go on treat yourself, I know they are expensive, but they are worth every penny, you will not be disapointed.

4.0 out of 5 stars Adios, Pot-Belly! 31 Oct 2009
By Lily_M
I have been using the belt for 5 weeks for 30 minutes a day in conjunction with a healthy diet, but no additional exercise as I am ridiculously busy. Even with this minimal effort, I have noticed an improvement in my posture due to stronger core muscles. I have also started to see a little bit of definition and my stomach is nice and flat for the first time ever! I was dubious at first; as while you can feel the muscles contracting during use, there was no pain the following day like you get with 'normal' crunches. I kept upping the intensity but I would still feel fine the next day! Now, though, I can see the difference and know for sure that it is working. It only took 3 weeks before I could see a change, and I intend to persevere until I have abs to rival any celebrity!
The only down side is that the batteries don't last that long, and that the belt doesn't go quite tight enough for me. Might be worth adding another bit of velcro. The pads, I am assured, can be made to last longer with water-based lubricant; and without that should still last a good month or so. I would recommend this product to anyone wanting to improve the appearance of their stomach; I've hated my wobbly pot-belly for years and nothing shifted it until now. Thrilled with the results :-)

3.0 out of 5 stars a bit hit and miss 17 July 2007
Verified Purchase
I have been using the slendertone for 3 weeks now, i think there is a slight improvement in my stomach tone-but i must say i have been dieting also- so don`t expect dramatic results.The one thing that i find most annoying and confusing about the belt, is there are no real indications as to were to position the pads on the belt-there are no waist measurements guidelines to follow, only very vague guidelines such as large,med or small. Due to this i wonder if i am getting the best performance from s.tone or if it is targeting right areas of stomach and waist, maybe if there was i`d be writing a fantastic review with a lovely flat stomach! I don`t regret buying it though, can feel it taughtening muscles when on, but overall a bit hit and miss.. MORE INFO SLENDERTONE!!!
