What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Shaking up the Hollywood blockbuster

For a good few years now I’ve been trying to source a Buttkicker wireless kit. I’m happy to say that I finally managed to get hold of a pre-owned one through ebay so I’ve made a video my experience.  


The Buttkicker store can be found at but as mentioned in the video, stock levels are depleted. There are alternatives but they may be a bit more complicated to set up....

I wonder if you set a jar with oil or water on your couch if it would vibrate demonstrating the effect? There might be a cellphone app or other electronics that detect vibrations,

When I worked for Odeon cinema in the west end of London, a film called Earthquake was released in something called Sensurround. (Forgive the spelling )The film distributor installed a massive Cerwin-Vega subwoofer in the cinema which kicked in every time the earthquake happened. The idea was to make cinema audiences experience the feel of a real earthquake.
I don't think the idea caught on because of worries to the structure of the buildings the sub woofers were installed in and lets face it Charton Heston was no longer the super hero he was being sold as to cinema goers.
The same system was also used other films

FWIW, ButtKicker seems to have updated their website references, so now takes you to their updated site: has items for sale and new products.

Does the thing work on other furniture like beds? What does it sound or feel like in the room below your ButtKicker? Do the low frequency vibrations carry?

The sites are still out of stock. Buttkicker got in touch to tell me they hope to have stock in late spring.
I'd expect it would work on a bed...however aren't mattresses supposed to absorb movements so one person rolling over doesn't wake the other. Then again there are foam or spring mattresses all of different tolerances so it's impossible to generalise.
I have installed mine in a detached house on a ground floor that is made of concrete and there is no cellar.

What happens if you plug the USB receiver into a computer? Is it an actual USB device, or are they just irresponsibly using the USB connector port as a simple way of sharing power and a basic signal?

I loved your review of this. I've always wondered if these types of devices were any good and suspected, like you found, that it's good, but less is more.

This review, along with 'MiniDisc - An Appreciation' reminded me of my Panasonic Shockwave CD player. This line of products had the vibrating headphones and 40 sec. anti-skip.

The first generations of these products were far superior then later models allowing control of the vibration with a dedicated amp and dual transducer, one on each ear. The later versions were much more gimicky, vibration always on or single transducer sitting on the back of the neck. I'm having a hell of a time finding the model numbers for the particular tape and CD player I had. The tape deck is RQ-SW70 and the CD player is SL-SW415, but the tricky bit will be finding original headphones that still work.
