Review (4/5): Epilator:  Fantastic.  "Spa" brush: Meh.
Pros: Nifty brush attachment
Silk Epil 7 is a great epilator even without accessories
Brush attachment feels fantastic on tired feet
If you are prone to ingrown hairs, this might help exfoliate to keep them at bay. YMMV.
Silk Epil 7 has a light to show you what you missed. Apparently, with my non-lit epilator, I was missing so much that I'm a bit embarrassed.
Cordless (once charged) for your hair removal wanderlust.
Massaging rollers on the epilator head really do make it less uncomfortable (they seem to distract nerves just a little)
My hair grows in much finer and lighter in color. YMMV.
Cons: Brush is only for the body NOT FOR USE ON THE FACE!
Brush is not friendly to my sensitive skin
Brush pops off too easily during use
My advice: If you don't have a Clarisonic brush (with the body brush head), you might like a motorized shower brush. If you really don't care about the brush, you might want to take a look at the other Silk Epil 7 packages out there. Some of them have more or less accessories, and different price points that may be more or less appealing than this Spa package, some have facial hair attachments and some have an electric razor head/accessory. It's up to you. I do recommend the Silk Epil 7 though, but Braun offers enough of a variety of packages that include the Silk Epil 7 that you can get exactly what you need.
Lengthier review:
The "Spa" Attachment:
This is not my first epilator. In fact, this is my second Braun Silk Epil 7 Epilator. My previous one was not part of a "SPA" package.
I adore the Silk Epil 7. I used this model before I got the Spa set: [[ASIN:B0077PLNB6 Braun Series 7-7181 Silk Epil Wet & Dry Epilator 1 Count]]
I still love the epilator portion and think that the little "headlight" and the bumpy rollers make things more efficient and less uncomfortable (uncomfortable if you have previously epilated or painful if you are a newbie to mechanically ripping the hair out of your legs). The Silk Epil 7 handle is comfortable to hold, it is wet/dry, though I do not like wet epilation (it just doesn't do as thorough a job, for me as doing it dry). I have tried other models from Braun and this one: [[ASIN:B004KMIZK6 Emjoi Optima Corded Epilator]] and at first I thought the Emjoi was the cat's pajamas, but the Silk Epil 7 (and even the 5) is far superior in regards to features, discomfort, and efficiency. I have not even looked at the Emjoi since making the move to the Braun hair rippers.
About the brush/spa attachment:
The "sonic" brush head dresses up the body of the Silk Epil 7 so it sort of looks like one of those Clarisonic type brushes. At first I was excited that this would replace my Clarisonic and be a space saving and effort saving 2-in-1 extravaganza. Such is not the case. The brush head/attachment for the Silk Epil 7 is strictly for body only and NOT FOR THE FACE. The brush head is good for regular body brushing/exfoliating to help prevent ingrown hairs (something I have never had a problem with since I started using an epilator, but many people do have that problem and an ounce of prevention is worth a pound of cure). I wanted to use it all over, not just where I used the epilator, and it feels fairly strong and abrasive compared to the more gentle (and quiet!) sounds of my Clarisonic with body brush head. I came out of the shower and was bright pink. My sensitive skin does ok with the Clarisonic, and fine with an exfoliating washcloth but the Silk Epil brush left me bright pink and feeling like I spent the day at the beach. It did, though, make my feet look quite smooth and the sonic vibration and brush were strong enough that my tired feet did feel pampered, though my legs looked about the same. Perhaps other users find the brush more helpful if they use their Silk Epil 7 in the shower. I prefer to epilate dry skin/dry hair, so the only reason I would take it in the shower is to exfoliate the rest of my body, rather than as an adjunct to exfoliation. The brush assembly/attachment was not that friendly as far as being able to angle the whole device to exfoliate my back and the head kept popping off, which was rather annoying and made me think that it is meant more for just the legs (and if just for the legs it seems almost excessive, but some may benefit from the sonic brushing to prevent ingrown hairs- potentially...).
