I did a fair amount of research trying to find the right dash cam for me. I had a list of features I wanted/didn't want. Initially I wanted a 2-cam system, but it seems that the technology available to rivals having two single-cam units. I decided to only get one cam to see how I liked the whole dash-cam thing and am very pleased with my decision.PRE PURCHASE CONCERNS=======================* The 'wedge' shape - initially I wanted a more discreet cam and felt that the wedge was both non-discreet and sort of ugly. The camera just looked big and bulky. I was REALLY surprised with him small this camera is... it's tiny.. TINY. The cam easily fits in the palm of my hand and I can almost close my hand around it..oh, I have normal sized hands. I really can't oversell how little this thing is. With it being so small the wedge shape actually doesn't bother me as much. When attached to my windshield you don't realise that the thing is shaped like a wedge because it conforms with the angle of my windshield.* The screen - I wanted my cam to be small and discreet so a screen was something I was NOT interested in. Typically screen-less cams have a mobile-app you can use. I wish the SG9665GC was screenless, but this wasn't a big deal at the end of the day.* Separate GPS module - I absolutely wanted GPS and thought it was odd that GPS was included, but as a separate module that plugs into the cam. On one hand, I can no appreciate having it as a separate module because it reduces the size of the cam and lets you put the GPS somewhere else. On the other hand, it was just one more wire I had to deal with during installation. Ultimately, I am glad they made the GPS unit as a separate module.. it allows the cam to stay super small and lets me position the GPS wherever I want for best reception. As a side note, I did do the GPS modification that flips the GPS guts upside down so that you can mount the GPS module to your windshield without reception issues.. this was SUPER easy and videos can be found online explaining how. I do wonder why Street Guardian doesn't just have it configured like this by default.* Lack of swivel/pivot/rotate - once positioned the cam's lense can swivel to point more up or more down. I was concerned about not being able to also turn the cam left or right or being able to rotate it to point inside the car if I wanted it to. Once the cam was installed and I got to witness the HUGE field of view the left/right swivel wasn't a big deal. I do wish the camera or it's mount allowed for the ability to rotate to see inside the car but this wasn't a big deal. The cam basically just points in one direction one mounted, but you get a very wide field of view.WHAT I LIKE==========* Price point - For the features included I really feel that this cam is outstanding. There are some other popular cams that cost double what I got the SG9665GC for that look cooler, but don't really provide anything better.* Picture quality - it's great. The Sony sensor really is the best out there right now and there's very little I can complain about. It was very bright and overcast yesterday so the sky was a little washed out at times (when driving towards the sun), but this didn't seem to be a fault with the camera, but more a result of harsh conditions. Video at night seems to be very good. There are some cams that seem to do a little better in this department, but I think the SG9665GC still performs very well here and overall the day & night quality is exceptional.* Size - like I said before - this thing is small! I have it mounted next to my rear view mirror and it's barely noticeable from the outside. I think people who see it might actually thing it was something other than a cam because it's so small.* Fast bootup - the cam indicates that it's recording before my stereo starts playing... usually it's recording before I have started backing out of my driveway. I doubt they can get this thing recording any faster.* Packaged goodies - the SG9665GC comes loaded with stickies, mounts, wiring, and everything you will need to get this thing up and running. The cigarette adapter (12v) to mini-USB (5v) cord was chopped up when I hardwired my cam to my car. I cut the cigarette adapter side of the cord off, soldered a inline-fuse (5amp) wire to the positive cable of the cig-adapter (black=ground, red=pos) and connected that to a switched 12v line my sunroof/rain-sensor control box. I attached the ground wire (black) of the cig-adapter to a ground in my car and I was good to go. Anyone who does this is obviously doing this at your own peril. The cig-adapter wiring is VERY long -- almost too long. I ended up having to hide a LOT of cable in my headliner, but this was easy to do -- and I'd rather have more cable than I need than not enough.WHAT I DON'T LIKE / WHAT SHOULD BE CHANGED========================================* The GPS wire is exceptionally long and it comes with a very short extension cable. I don't understand the point of such a tiny extension cable. It would be nice if the GPS cable detached entirely from the unit and you could attach JUST the smaller cable. In my install the GPS and cam are right next to each other and the feet of GPS cable had to be hidden in the headliner.* Error notifications. If the cam starts without a memory card in it there is an error message that stays up for a few moments, but there is no audible notification. In my install the cam is to the right of my rear view mirror so that when I'm driving I can't actually see the cam. If there is ever a problem with the cam or memory card I most likely won't know. There should really be an option to have constant beeping if there is an error. This could be done in a firmware update and could be disabled/enabled via the menus* Lack of an app/wifi - It slightly annoying having to remove the memory card if I want to view the videos. It's unlikely that a firmware update will allow for wifi in the future (no wifi hardware), but v3 might consider including this option* The MicroSD slot is impossible to use with your fingers. This is one of those 'push in' to pop the card out type of slots. The problem is that the slot is just too small to press the memory card in with your finger. I end up having to use a small coin to press on the memory card to insert and release the memory card. A small gripe in the grand scheme of things - just an annoyance.* The cam's 5v requirement. I cut up the cig-adapter cable in my hardwire installation because it included the circuitry that converted my car's 12v supply to 5v for the camera. The issue is that I now no longer have a cable I can use for the camera in another car (the cam is removable from it's mount allowing you to take it with you in another card). There are easy ways around this (get a micro-usb cord and a generic cig-adapter), but it would have been helpful if the camera body included the 12v->5v circuitry.======The main driver for my purchase was that the picture quality was reported as being one of, if not THE, best on the market. What good is a dashcam if the picture isn't good enough? Other reviews cited that this product is very well-made and that customer service is great... I can't speak for the customer service, but the cam is absolutely solid and packed full of features. For the price it seems like a steal and I plan on getting another SG9665GC v2 for my rear cam and for my wife's car
