Initialy I rated this product five stars (but read the rest of the review). (Moreover, I then gave it three stars, but, regrettably, even that was too much, as I eventually discovered.)
I just got the second shipment of this stuff -- it seems great (so far: and I'll update this review if I have anything new to say, good OR bad). Both times it came very fast, packaged well (in a cardboard box holding four plastic bags, each holding over half a kilo of these seeds). The quality seems very good, good taste.
I add these seeds to oatmeal, and actually, just eat them straight quite a bit: I just walk around with a bag in one hand and a spoon in the other :-) . Unlike flax seeds (which are nothing special), sunflower seeds are really tasty, so I have to stop myself from finishing off a whole bag in one sitting.
I used to buy them in our store here, but those are salted and fried, so I figured one day, I get a ton of salt every time I gorge on those seeds, so I googled for unprocessed seeds, and lo and behold, Amazon has them (at a better price too). I've never bought food here, but this turned out to be a very easy option, no-hassle quick delivery: one day you simply find your order on your porch... the stuff isn't easily perishable, so that works fine. I gotta say, as much as I detest Amazon's obvious love of fake five-star reviews from publishers' shills, when it comes to variety and order fulfillment, they're very good, addictive really.
I see some reviewers mention another supplier of these seends -- thanks for that; this is something to try in the future. For now all I can say, Red Bob's sunflower seeds seem (taste) pretty good to me. Supposedly they're very healthful, but even if it's all hype, they taste good enough to eat them just for that. And of course, if you don't like them raw, you can fry them yourself, w/o a lot of (or any) salt.
01/08/2011: I'm on my third refill now, and I'd like to issue a warning: a couple of packs contained real hard bits, something you could break your teeth on. Very rarely, but still. I fished one out to see what these thingies look like, but they're really undistinguishable from the normal seeds: same form, size, and colour. This taught me not to chomp too heavily... I'll get one more refill: if this is an isolated phenomenon, OK; but if not, I'll drop the brand. Otherwise all's good though, great stuff.
02/16/2011: Refill seems fine, no hard particles.
04/08/2011: I have to bring the stars down: every fourth or fifth bag has slivers of shells and small solid particles amongst the seeds. Shells, at least, can be picked out visually, but the solids are the same colour and size as the seeds (impossible to discern, though their shape is slightly different, more squarish) so there's a serious risk of chipping a tooth -- a bad bargain, imo. Mostly these seeds are good, but now and then there's a bad bag. Not sure how to deal with this... I like these seeds, but then I like my teeth too. Will probably give up this product.
05/25/2011: Yeah, I quit buying it. Hopefully I can find another brand that's not as dangerous for my teeth! :-) I'm buying a number of products from this "Red Bob" outfit, and I'm happy with them all except this one -- I think the company needs to concentrate on quality control (instead of jacking up the cost: I just noticed when posting this that the stuff went up quite a bit, like fifty percent -- dear maker, as it is, it's not good at any price if you value your teeth. And btw, loose sunflower seeds, unprocessed, are available in stores, for example at Wegmann's for three-ninety-nine a pound, Whole Foods for two-ninety-nine a pound, and Trader Joe's for the amazing buck-forty-nine a pound -- and you don't have to get five pounds to get this price.. be watchful about prices, always: observing this site I see many items go up by the mind-blowing thirty-to-fifty percent overnight... somehow my salary doesn't go up like that, 'specially in the midst of a recession, um, sorry I forgot it ended two years ago, purportedly).
