Sleek and lightweight
First I want to disclose that I was reimbursed for this purchase in return for my review. The first thing I noticed was that the unit was very slim and lightweight.  It came with a USB micro connector and adapter.  After plugging it in,  I noticed the timer. It can be set for 30 seconds or 60 seconds.  The gel products that I used required 90 seconds and 120 seconds respectively,  but it is easy to just hit the button again to add more time. The unit is highly portable and could easily be taken when traveling.  The only reason I gave it 4 stars instead of 5 is that after using it for the time recommended by the gel products,  my nails felt a little  tacky. That being said,  it could be that the fault was with the products or that possibly I used to thick of a layer. Overall it is a great product for the price and will get the job done.
