Compare REVIEWS: Flash N Go vs Tria vs SensEpil

Flash & Go REVIEW

A user who reviewed Flash N Go says that after the third treatment it slowed hair growth. It works on underarms, bikini line, arms and face. It needs care and lowering of settings or it burns small areas. Another reviewer says that they opted for the $300 worth device to expensive laser treatment but they were not very impressed after a few uses. The reviewer has a very fair skin and dark and coarse hair and the reviewer expected better results. They started the first treatment in June and by October they didn’t see any results. The instruction book mentions that after the 7th treatment a user needs to use the device till desired results are achieved. But the book doesn’t mention what a user should do if results are not achieved even after the 7th session. The reviewer expected to be hairless after over three months of use and completing more than seven treatments and following the instructions perfectly.

When the reviewer got in touch with the customer service of Flash N Go, they were asked to continue treating smaller areas on a weekly basis and treating larger areas on a monthly basis. The reviewer continually used the device on underarms, face and bikini line weekly but there was no change. Their legs seemed to get patches of hairless skin but it was much beyond the 8th session. The user suspects that it would take them as long as up to a year to get rid of unwanted hair completely if the device were used to its full functionality.


Silk’n SensEpil Hair Removal REVIEW

One customer, Aurora Brown who used Silk’n SensEpil Hair Removal says that there have been some minor visible results on using the device for several months. The customer has experience with professional laser hair removal, which worked wonders, and hoped Silk’n SensEpil Hair Removal would work similarly. The customer states Silk’n SensEpil Hair Removal does not really work as it claims. It’s not easy to use and does not have enough juice to uproot hair follicles. But since it made some slight difference the customer is optimistic about using it. But the cost incurred on the device and the refill along with time taken is as good as getting a professional treatment done. April, another customer who bought Silk’n SensEpil Hair Removal reveals that the initial cartridge that was shipped with the device did not work more than 100 flashes as opposed to the 750-1500 flashes expectations. Upon complaining she received a replacement which also worked for only about 100 flashes. The customer is disappointed as it increases the cost of using the device. Another customer, Courtney, who purchased Silk’n SensEpil Hair Removal complains that it is not really a hair removal solution. In fact, it is more of a hair reducing device over permanent solution. It does provide noticeable change and reduction in the amount of hair. In some cases after using it the hair grows back exactly with same thickness but with platinum color, which is weird. The customer has similar complain of cartridges running out soon and their cost being high. The customer advises to use Silk’n SensEpil Hair Removal on level 3 as it can pain on higher settings similar to professional treatments. The device does work but requires a lot of patience to use it and using it on lesser level means more time and work.


Tria Hair Removal Laser 4X REVIEW

Cynthia, a customer, who tried Tria Hair Removal Laser 4X, complains that it is a waste of hundreds of dollars as it fails to deliver what it promises to. She didn’t notice any concrete results despite having standard fair skin and brown hair, which work well as per device reviews and claims. On active use as per the guidelines of the device the customer noticed only a small patch of hair gone. Treating all the parts on the highest level did not yield great results as hair still existed on other parts of the body. After stopping active treatment the hair also started to regrow. Even though it may cost less than treatments at a clinic, it’s still expensive as it simply fails to perform. One another customer, Karen, who bought Tria Hair Removal Laser 4X says that it till now there have been no substantial changes in the hair growth. Her facial and body hair reduction is a concern due to thick denser hair on a fair Latina body. The customer says that the device is painful when it works even after buying the numbing cream and taking two Advil. The manufacturers do claim that the pain subsides after few use but isn’t true in her case. With use for over 2 months on a weekly basis there has been no change but it is too early to agree or disagree whether it is worth the money and pain or not. Nancy, one other customer who reviewed Tria Hair Removal Laser 4X noticed subtle difference in hair growth but says it is not worth the money. When compared to spa treatment, the device has many drawbacks and lesser capacity, even with the highest level setting. It is painful too and is only goo for touch-ups in between sessions but not the solution for hair removal.
