DealExtreme: Card Reader SD / SDHC / MMC / TF Pisen High Speed ​​USB 2.0 (Pisen High Speed USB 2.0 SDHC SD/MMC/TF Card Reader)

Recently I made a purchase in DealExtreme de to card reader of Siyoteam, that came with defect, functioned as read only. After contact with DX, they offered a replacement, but fearing that all had the same defect Siyoteam asked them to send me the Card Reader SD / SDHC / MMC / TF Pisen High Speed ​​USB 2.0 (Pisen High Speed USB 2.0 SDHC SD/MMC/TF Card Reader), I'd just be included in the store, in the hope that it would work better. The Pisen is even cheaper than the Siyoteam, and the DX agreed to my request.

The card reader of Pisen came in a plain packaging, cardboard blue and yellow with a sturdy plastic shell. In front entries “Pisen” and “SD”, besides some inscriptions in Chinese. On the back some specifications: model lê cartões SD / SDHC / MMC / MMC II / RS MMC / Ultra II SD / Extreme SD / Extreme III SD / Mini SD (with adapter)/T-Flash Card (with adapter). Support Windows 98/ME/2000/XP/Vista or MAC OS 8.6.9.X or higher. It also supports the function “Ready Boost” Windows Vista. Its speed is 150X, the speed of which varies depending on the CARD. Still in the back has a boy with a happy face with a camera in hand and some inscriptions in Chinese, he would be a famous photographer in China? A date also appears above the barcode: 07/01/2009, probably manufacture date.

The disadvantage, relative to Siyoteam, Pisen does not directly reads microSD, which is not a problem for me, because only microSD use on mobile and I record it for Bluetooth. The reader has two caps, one to the USB port and one for the slot cards. Unlike Siyoteam, this reader you can close the cover with the card inserted, which is useful for those who want to use it as a stick sometimes. The translucent blue plastic allows you to see the internal components, the circuit board brings inscriptions with the manufacturer's website:, a inscrição “SD_REEADER_SM331”, where SM331 is probably the model. Pisen the card readers are found only in the Chinese version of the site, which is also one driver para Windows 98 downloadable. Although the circuit board have entries “See:00”, “0850”, “Pisen_SD2” and “ROHS”.

Considero that the results were good, as he came to 131X, near the nominal 150X. The remaining steps are for reference, the manufacturer does not specify anything other measures in no way compare. But the experience of copy / remove files it seems to be very good.

A DealExtreme made the submission in 09/02/2009, Without Registration, as is common in replacements, and only reached on day 04/03/2009, almost a month later, the package including the registered Kit Transmissor/Receptor de Audio e Video Gadmei, sent after that eventually came before. The package was inspected by the IRS to Curitiba, as the stamp that indicates it was released, without taxation. It was used to label the Drop Shipment, no content description, the declared value was 19 Hong Kong dollars (HKD) and the package was marked as present (Gift). The IRS Curitiba often taxing virtually everything that goes on there, then the question is what this package of card reader that has got through unscathed, I would point two factors: a) Unregistered is a package and b) is a small package and low volume. The first case is not the first time it happens, because dedo of mouse + battery pack that were also a replacement Without Registration also passed unscathed. The second case also occurred before, with a package 4 Batteries, registered, who also went unscathed, probably because small. I do not want to risk with unregistered packets on future purchases, since the mail here have gone with two of them, but it is good to know that small things (as batteries and related) are spending without taxing. On the other hand there have been cases of cheap packages taxed with value above fair, and this can be a pain-in-the head more to ask for review.

In short, note 10 for a DealExtreme more successful an RMA, ponto practical Pisen, by the Card Reader SD / SDHC / MMC / TF Pisen High Speed ​​USB 2.0 (Pisen High Speed USB 2.0 SDHC SD/MMC/TF Card Reader) at least initially is working perfectly. And another big ZERO for the Brazilian federal government because, even if that packet has been released, we know that for those who live within SP remains a dilemma buy the DX because of the taxes that the Federal Revenue of Curitiba applies in almost all.
