Lithium Battery Failure Rate

This lithium battery is very reliable.

I have never been disappointed in the results I've had with Verbatim media. I've had about a .5 percent failure rate. Can't say the same for other brands I've tried.

I was somewhat concerned by other reviews about some quality control issues with these units. One out of four that I ordered did not communicate with the controllers in radio slave mode. I returned it and it was promptly replaced with one which did. I bought 2 kits with controllers, and 2 single units. Having seen some of this manufacturer's less expensive units I was happily surprised with how well-built these units are. While I don't for a moment discount the significance of a 25% (20%, if you count the replacement unit) failure rate (how can they stay in business at that rate?) I can also say that they do all they are advertised to do, at a fraction of the cost of other radio controlled units. At a cost of less than 1/6 of a name-brand unit, I can even afford to risk a failure (or accidental destruction) in one of these at a rate I could not sustain with the name brands. I have been able to work up a protocol for ganging them with my older Bolts (and presumably any other unit which will fire on an optical slave) which is efficient and gives me more functional units. It works even when the purely manual units are within a sealed environment such as a softbox designed for use with speedlights.

[This review was collected as part of a promotion.] Good product, very fast speed and 0 failure rate so far.

There are many brands of drives that I avoid for their high failure rate, and as they increasing become manufactured by the same company, it can be hard to avoid the,. Synology is new to me, but anything is better than the popular brands that I KNOW are going to fail. We'll see how it goes over the long term with this one.

I am hoping these will be back in stock as I use a lot of these and love that the failure rate is very low - maybe 2 out of 100 or so - not bad compared to outer brands.

I previously went through a couple of hundred Mitsui/Mam-A discs, which had a reasonable but still detectable failure rate; so far these have been flawless. Burn rate is relatively slow, which seems normal for archival DVDs. Packaging states they're un-compatible with 1X/2X speed drives.

Amazing for VIDEOS & PHOTOS Storage although you need 2 of them in case of a failure (BACK IT UP) for everything's in the universe fails. Its large storage could go a long away and it is a USB 3 for faster transfer. The transfer rate it depends on the compression of the VIDEOS. The higher the compression the slower the transfer rate. I note that it goes down to 78 MB/s then it stays. although the higher was 150 MB/s

The failure rate is low on these. I use them to give clients a copy of their tax returns. Very low failures. I especially like them because i can print my logo and a background all the way to the center of the CD. Looks like i had them professioally printed.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.
