Product seems reasonably well built, but I'm left with several questions: * How to get it to read a USB drive? * What format does the USB drive need to be in? * How long would it take to read a USB drive? * Does it support folders on the drive? * How many bits does the decoder support? * Why does the battery cell connectors read 5V when a USB drive is connected? You only needed a single diode to solve this problem... I'm currently trying to get it to load MP3 files from an 8GB USB drive formatted to FAT32 with all of the MP3 files in the root of the drive - nothing heard so far.

Seems to be of reasonable build quality. The soldering end is all metal, everything back from that is plastic.

Not bad. Build quality seems nice, fit in ears nicely. Only complaint is that with some devices the signal can be weak and cut out music.

Nice and strong, seems to be as described. Just be careful of the metal filings.

Item arrived fast and appears as stated. The M3 and M4 nuts/bolts I tested appear to be standard (have the right thread). The box doesn't look as full as in the picture but from what I could tell there is the correct number.

The product looks great and feels great. It came in a very good packaging for shipping, so zero damage. The cable is not great quality, but is okay. The sound quality left a lot to be desired, from testing it varied greatly from which 5V power supply I used. Knowing that it really consumes very little power, I decided to mod the cable and solder a small capacitor across the 5V lines - this greatly improved the quality of the audio. This feels like something they should have done themselves inside the microphone. I wouldn't be surprised if they just didn't solder a cap inside to save costs. The echo works great, but the volume is awful - it's literally all or nothing at all. Whatever resistor they are using for the voltage divider is way too high. I'm half tempted to bypass it entirely as the audio isn't very loud as it is. The microphone in general does an okay job at filtering surrounding noise. It's a massive upgrade to my headphone and laptop microphones, but there are some really small things they could easily do that would make this a much better product.

It's pretty hard to mess up a product like this, USB hubs are well understood. Not tested it to the full speed yet but seems okay. One thing that would be nice would be some intelligence, like trying to figure out if too much power is being used from the port. Maybe have some DIP switches for power rating and a current sensor inside. Then just a few LEDs to indicate how loaded the port is.

A little cheap, some scuff marks on the controller as if it's been dropped. But seems usable for my purposes.

Used for ink, did the job fine. They don't seem medical grade though, so don't think about using them for anything else.

It's actually been a pretty good conversation starter in the office. Also, good to use as a reference when working out which pads we wanted on our PCB!

I haven't fully tested it yet, I made the mistake of thinking I could use it on a 1 cell battery. I wish this device would support that. One thing I do hope is that when left in for long periods of time it discharges the cells evenly - otherwise it could make a balanced LiPo become unbalanced.

Nice to type on, works every time. I only wish it allowed for me to attach a LiPo battery. Other than that, awesome product.

Amazing at their price point. Connects fine with a phone. A few things that could be fixed in new designs: * Longer battery life (or maybe an option to upgrade it) * Bigger buffer for songs * Better antenna/receiver (it's quite easily overwhelmed) * The low battery warning shouldn't pause the song and it shouldn't be so loud * The cable on the folding part of the earphones is really weak - this should be a little better protected Overall though, great product. Sound quality is surprisingly okay for the price.

Good points: * Back light is three colours, adjustable brightness * No drivers required to use the keyboard (it's just standard) - worked out of the box * Arrived quickly * Packaging seemed adequate for this type of device Problems: * Arrived with broken plastic case (plastic seems *really* low quality) * USB wire hanging out * Keyboard flexes when you press a button hard * You have to press buttons hard for them to register * Sometimes buttons get jammed when you try to press them down * Key back light is very dim at 100% because the molding is not great For $30NZD I would actually expect better than this. It's not suitable for a gaming keyboard at all (I tried an FPS).
