For the money this kit is a fantastic start for a short and minor disaster. I'm giving it 4 stars because I recognize the price and that no kit put together for large quantity sale will be perfect or high end. What follows is a list of criticisms though to help people who buy it round it out or know more about what they're getting. This is NOT a Bug out Bag, and a good BoB will cost you $1,000 to put together not even including weapon. I got this kit as something that will hang out in my vehicle full time (water and food in winter or peak summer months could be an issue here, still strategizing on that, e.g. keep a smaller bag with those components at work) and provide necessities to help get me to a BoB or home should things go awry while I'm on the road or at work.
The backpack has "Survival Kit" on it in large yellow letters. This is dumb, you know what it is and you don't want people who don't have one of their own to know what it is. For now I've taped it over with black gorilla tape. I'm thinking about a better solution including making it look like a college student's bag. Imagine for some reason you are forced to walk home or to a designated shelter, and things happen to be causing people to be irrational, you do not want a big target on your back.
The 5-in-1 survival tool is complete crap because the compass for me was DoA (this is the -1 star). This is very dangerous for someone who needs it but didn't test it when they got it and on a regular basis. A good compass though costs more than this entire kit. I moved half the matches to the inside of this tool, just to be located elsewhere and a bit more water resistant. Don't forget you still need the striker on the box. I threw a bic lighter in the bag as well.
For some reason I got an entire extra box of no name band aids, I didn't see it in the product description. That's kind of nice, but I removed it. No one needs 30 standard band aids in a 3 day kit. Instead of the small n piece first aid kit I'd rather have quick clot and a compression bandage. The things that standard first aid kits do for you basically boils down to unnecessary comforts in the scope of a 3 day disaster bag, aside from covering some inconvenient cuts at best. Wear the gloves. It's a logical addition though (the small varied kit, not the significant box of one bandage type)
The water supply is 3 day and 4 person only in the sense that you have iodine based water purification tablets (50 quarts worth) and there are 4 plastic pouches with spouts that each contain 6 ~4 ounce water packets. After you remove and exhaust the packets the pouches can be used to gather water from a source and purify it. Otherwise ~26 ounces of water per person isn't impressive for 72 hours. If I was building this kit I would probably do the same though, at most I'd bump it up about 50%. Water is heavy.
The food supply is a bit thin at 800 calories per person per day by any standard. Yes I realize this is "survival" kit, but I still think 3600 cal bars would have been a nice touch.
My D batteries have a use by date 2 years shy of the food and water expiration.
The bag leaves little room for your own additions, which I imagine people will have some. I've added a full tang hunting knife, Gerber multi-tool, quikclot trauma kit, bic lighter, and 8oz hand sanitizer (many uses). I have other things in my vehicle so they don't need to be in the bag, wet ones, fire steel, compass, hand/feet warmers, small but powerful flashlight, q-tips, tissues, toilet paper, ibuprofen, antacid, boots, gloves, baseball hat, outerwear-warmth, and outerwear-rain (additional gear in winter season also). A few of these if not in vehicle where bag is used I would include in the bag itself; especially fire steel, good compass, and toilet paper/tissues.
On the average the quality of all items, as expected, is low. What do you expect though, put more stuff and better stuff in your BoB or house.
This is no substitute though for what you can inexpensively do at home, rather a nice addition or best on the road. Realistically bottled water is supposed to have an indefinite shelf life, you can easily keep gallons per person stored at home. In addition your house presumably has a couple weeks worth of food all about.
I expect the honey bucket kit to be more common in the house, this backpack kit seems more like a compact and practical mobile addition or at work in the locker/desk.
If you are truely looking for a grab-and-go bag away from home and do not plan to build real BoBs (outdoor survival of undetermined length, as opposed to 2-3 days) for up to four people that you will not augment too much then this seems to be a much better choice: http://www.amazon.com/Survival-Earthquake-Evacuation-Emergency-Preparedness/dp/B002H5Y9YY/ref=sr_1_3?ie=UTF8&qid=1335747080&sr=8-3 are you really going to scoff at an extra $35 per person for making it well through a short disaster experience?
The earliest, simplest, and cheapest differences between the Mayday kit here and my BoB are a part of this other kit. e.g. mylar sleeping bags instead of mylar blankets, e.g. hand crank equipment.
I will update this if I experience any quality issues around the food or water in the future.
