The flame version is often the favotire choice. I don't nor plan to get any of those. If you do be sure to get the protected ones.
At the moment im only buying Hi-max 2600mAh form ebay which are a realy value for money. Ocassionaly i can get XTAR 18700 (same thing as 18650) locally if i'm in heavy need. Also good stuff and not expensive.
Never tried solarforces and those are quite more expensive so i stayed clear... also good by reading here on BLF.
Reliability is about on par, but DX is slower in both shipping and service, plus they tend to lie a lot more and are routinely doing stuff like issuing fake paypal refunds if you open a dispute.
Recap: KD is faster and more honest at the moment.
Kd is going strong lately in shipping times. I only miss the frequent lack of communications. If he reply to my mails usually ends up a good deal for both if he does not im looking elsewhere. I wish he would take time to reply to my mails and im not really spamming him. Very few and very short. Often no reply. It seems when he feels to it does otherwise not. Who knows...
KD's availability info is way more reliable than DX's one, usually they ship in time and the only thing unavailable was immediately updated in the product page, the new arrival page of DX is a money trap beside the long list of products claimed as in stock when for months are not.
They catch me now with the ultrafire G10...order received, many thanks for the loan ..
my last order DX creamed KD..I ordered on Jan 28 from KD and sent them an email yesterday asking what date they sent it to the post office..I get a reply stating my items were packaging and would be sent out in a few days..lol it's been over 2 weeks and it's just now packaging? never again will I order KD..DX shipped mine out 2 days after they came back on the chinese new year..pretty impressive..
as for the flame trustfires..I have the 18650's and 16340's and they're all been great..would order more if need be without hesitation..
i've been really impressed with my trustfire flames off DX..took about as long to come from DX vs manafont..DX has registered shipping..manafont it's untracked or for 2$ more you can get registered..for 9.50$, the flame trustfires are about as good as you can get for rated capacity (for cheap cells) judging from the tests on cpf..
