for Samsung Gear VR (Compatible W/White 2015 Consumer Edition gen. 3 - SM-R322 ONLY) Satori VR Fan w/Built-in Rechargeable Battery by Asterion Products (Samsung Gear NOT Included)

As the title says, this review is basically going to be 2 sets of stars type of review. First, the important part of the review. The 5 star review. This goes towards the product itself. I just got it in today (11/14/2016) and I was stoked about it ever since I pushed the checkout button. If anyone else was like me at one point, I didn't give my Gear VR much love because I got so sick and tired of the overheating issue. To counteract this, I would sit in my room with my face towards my window unit to keep it cool for me to play it for a while. And yeah, it worked, but what about those times when I want to take it on the go and play it or show my friends? That is where the problem comes in. 15 to 20 mins, if I'm lucky, of performance play before it hits me with the overheating warning. And with most games, 15 to 20 mins isn't much time. Sometimes, I would sit my phone in front of my AC so it can be nice and cool before playing it. That maybe got me 25 mins on SOME occasions. Because of this, I didn't really play my Gear VR, much less take it anywhere with me. I stumbled across people making homemade fans, but I'm sadly not that crafty, and I have computer parts laying around my house. :-( Then I came across this one and another one on here. I was going to get the other one because of the different colors and a light up one, but I was okay with standard black. But the other one wasn't getting that great of reviews. So I came to this one and nothing but 5 stars across the board. I even found a Youtube video of someone showing this off. This thing is great. I got 20 mins of play and the only warning I got hit with was my battery running low. NO overheating issue at all and I'm planning on giving this another go later on when I get the open minute. If you want to show off your Gear VR but tired of the overheating issue then I HIGHLY recommend this product. It WILL be the best $35 you will spend for your Gear VR. Sure your phone still eats battery life upon VRing, but at least with this product you won't have to worry about overheating issues. After 20 mins of play my phone is typically really hot. With this? Barely even hot, barely even warm. A must have product, hands down.Now for the other stars review. The shipping time. This I will have to give 3 stars. The product is AMAZING and I'm not taking ANYTHING away from it. But I ordered this product early Thursday morning and clicked one day shipping, and I get a notice saying that my product wasn't coming in until Tuesday! I didn't change my shipping because there are a time or 2 that things came in earlier, but then it changed to Monday, rather than getting it on Friday, much less Saturday because I think Friday was a holiday. I sent out a question asking why I'm getting something on Monday when I ordered next day shipping on Thursday and no reply. And considering that my package was traveling around an hour away from me, while I live in Aiken it was all around West Columbia and Columbia, I would think I would have gotten it on Saturday at least. Nope, came in tonight at 8pm. So, I'm not sure if it is the seller, Amazon, or just UPS, but to pay for next day shipping and didn't even get it really pushed the wrong buttons with me.Besides that, a must have product for anyone with a Gear VR. PERIOD! 5 Star product!

It does exactly what it's designed to do, keep your phone cool. It does it very well. You can't even tell you've been using phone for Virtual reality. It gets 4 out of 5 stars simply because it's just a Lil heavy for me. In order to keep it from sitting on the edge of my nose I had to readjust my straps tighter. It's only a small nuisance but the headset is a bit more snug than I'm use to. I'm guessing I'll get use to it and eventually it won't even be an issue but for now it is. The bottom line is if you own a Samsung Gear VR headset, you need to own this fan also.(I own white edition from last year) It will keep your expensive phone protected from heat and basically preserve your VR experience. Worth the money and the extra weight.

I'm exceptionally pleased by this add-on to the 2015-version Samsung Gear VR headset. This is, simply stated, a MANDATORY part of a properly-functional Gear VR set.My main displeasure was that this was not part of the actual Gear VR as sold by Samsung in the first place. Any competent mechanical engineer would have determined, throughout the design verification stage of the development of the GearVR, that a secondary cooling solution was ABSOLUTELY REQUIRED for the use of this headset.However, Samsung failed to do proper design on this device. It seems that there are some improperly-educated engineers at Samsung, as a similar issue resulted in the total recall of the Note 7. They seem to have kids doing their design... kids with no real-world expertise (though excellent software skills). Competent design professionals NEVER release a product without thorough testing, and without a full FMEA process being completed (that's "failure mode effects analysis" for the non-technical readers here).Thermal analysis is a critical discipline for all mechanical design, but moreso when dealing with densely packaged electronics, and ABSOLUTELY ESSENTIAL when dealing with lithium-ion power cells... which, if overheated, can begin to decompose. This decomposition can result in a runaway condition... and produces its own oxygen, meaning that a lithium-ion cell, once it ignites, produces its own oxygen (meaning that you can't put it out except by removing heat at a massive scale, like hitting it with liquid nitrogen). They don't actually "explode," they just burn, hot and fast, and can't be put out. The effect is pretty similar, but it's not an "explosion" per-se.So... if you allow your device to overheat regularly... for any reason... the power cell will degrade far earllier than it would normally do, and you stand a much greater risk of a runaway condition... the "explosion" we've been told about re: the Note 7. To prevent this, you need to design in a cooling method which prevents that from ever occuring.The more computational power you pull out of your power pack... and VR is very computationally intensive... the more heat is generated in the power cell itself, as well as by the electronics which are doing those computations.And the thermal dissipation scheme in the Galaxy series phones... AND in the Note series tablets, for that matter... is not up to the task of preventing this sort of overheating when high-end VR apps.SO... where does that leave you?You need a secondary cooling means for your phone if you want to run VR. The "Google Cardboard" is lower resolution, lower fidelity, and requires less computational power, so you MIGHT be OK, for a bit longer, running a "Cardboard" type VR headset. But even then, you'll likely overtax your phone.SO... again... this is a nearly perfect implementation of what SHOULD have been provided with the GearVR (and with any other decent VR headset using a phone to do the work). A secondary cooling method to cool the phone.It's not as good as it theoretically COULD be... having the air blowing over a heatsink, in thermal contact with the back of the phone, would work even better than what we have here, but would weigh quite a bit more. As it is, this does the job quite adequately for my Galaxy S7 in my Gear VR headset. Instead of being able to run for ten minutes or so, max... I can run for hours (long enough to watch a 3D moving in the Samsung Theater app) or to watch multiple episodes of a TV show in the Netflix VR app... or to play a game for more than an hour straight (though few games will really allow that, as the "motion sickness" factor comes into play long before that for the vast majority of people!)It's a pretty simple concept... but it's very well implemented. It simply replaces the "dust cover" on your 2015 Gear VR headset (IT WILL NOT WORK ON THE 2016 VERSION, WHICH HAS A TOTALLY DIFFERENT FRONT COVER DESIGN).The camera window is nice... it only slightly interferes with the view range on my S7's camera... so "camera pass-through" applications will work fine. I'd actually prefer a 'clickable" or "slideable" switch to the touch switch, but most folks will appreciate the (more technically challenging) touch switch, I suspect. I just like the reliability of physical switches when possible. The charger, power cell, and fan all work nicely. The fan is not very loud (when wearing earphones you won't notice it, though it IS audible to someone next to you in bed!)The GearVR needs this. If you have a 2015 version of the Gear VR, DO NOT HESITATE... buy this immediately. If you have the 2016 version... I'd recommend you avoid using your GearVR for more than a few minutes at a time, until you can get something similar for it.
