Good Voltage Doubler
Simple way of turning a 1-Spot's 9v or 12v outlet port into, respectively, 18v or 24v. Used it for my Fulltone Secret Freq guitar pedal which can run at 9v or at 18v; the extra headroom it offers at the latter was well worth taking advantage of. I had used both 18v-outs on my CS12 brick, so I used this voltage doubler in a standard 9v port... and the pedal is even better as a result!

Does the job well... but at an extortionate price!
If you have a carbon 'tube' that you want to cut with a special carbon-fibre-specific saw blade - which are wider than standard 'toothed' saw blades - then you will find that the similar saw guides priced much cheaper are unsuitable; the Park Tool SG8 basically has a wider gully for the blade.
I thought I'd be clever and buy a cheaper one with a view to taking it apart and fitting a thicker 'him' to widen the gully, but try as I might, I couldn't undo the bolts that hold the guide together! So I reluctantly had to invest in the SG8 in order to cut down my carbon-fibre fork steerer tube.
The supplier of the SG8 is known to me and I received an outstanding service - fast despatch and item as described. No issues with them. As for the SG8 itself, it is solidly constructed... but, to be honest, no better than the cheaper alternative I had previously purchased. Still, as with everything Park Tool put their name on, it's most certainly NOT 'tat'.
But is it worth £40 - the full retail price? Absolutely not! I wish the copy-cat brands would produce something at half the price, because how Park Tools can justify this price beggar's belief. Okay, if it came with different shims so that you could adjust the saw gully width to suit (and thus make the SG8 more versatile), then that might make it better value. But before buying yourself this SG8, ask yourself this: "Will I use it many times to get my money's worth?" Because if the answer is no, then I'd say go down either of these two routes:
1. Keep scouring the internet because, at some point, you'll be able to find a cheaper alternative to the Park Tool SG8 (I couldn't when I needed one in April 2017)
2. Buy a cheaper alternative and use a standard saw-blade with a MINIMUM of 32 teeth-per-inch. From all accounts, the finer the tooth-count, the better the suitability for cutting carbon-fibre tubes.
Of course, if you're cutting only aluminium or steel tubes, then any guide will do... and there are PLENTY of much cheaper alternatives out there.

Essential for cutting carbon-fibre
I purchased this because I had a carbon-fibre steerer on my bicycle fork which needed cutting down. You 'can' use a standard hacksaw blade, provided it is very fine-toothed (minimum of 32 teeth per inch), but you do run the risk of 'tearing' the weave and thus compromising the strength. And given that carbon-fibre 'lets go' with catastrophic failure (as opposed to a gradual failure), it wasn't something I wanted to risk on my fork!!!
But not this: the CSB1, being carbon-fibre specific, doesn't have orthodox teeth. Instead, it has an edge consisting of diamond-like particles which makes it quite a wide 'blade' - about 1.5x the width of a conventional hacksaw blade. So if you're using a standard saw-guide, it may be too wide to fit the gully. That is why Park Tools make the specific SG8 saw guide... though that will add another 40 quid to the job!!! (I've done a review on that, too.)
And what about the CSB1's performance? Well, it fits standard 12in hacksaws without fuss, and remains well tensioned in use. It cuts carbon-fibre extremely well, without ripping the weave or 'drifting' off line. If you have an expensive carbon-fibre component to cut, then I would suggest the CSB1 is an essential piece of kit to have in your toolbox.
