I live in Denmark, I ordered the torch on 17th March and it arrived on the 23rd of march thank you everyone at Torch Direct for a speedy service. As for the torch itself, I look forward to having it with me on the pennines this year and also when I'm out kayaking at night.

Made to the same high standard as the TK75 itself, this is a perfect fit. The barrel looks like one piece rather than two joined together and the torch looks less 'stumpy', but of course, the best thing about the extended run time kit is that the torch now runs for weeks between charges. More relevant to most though, is the fact that it lasts a lot longer before reverting to high power from turbo (the only niggle I had before). All in all, well worth the extra outlay.

Works but

I have a TK75 and bought the extension kit to go with it, firstly the extension and components are well made as is the TK75 , the extension gives the torch a fantastic run time and also balances the torch very well in the hand , one gripe thou when all loaded up and screwing the end cap back on the cap won't go all the way home its just under a 1mm gap as it clamps all the holders up tight, when the torch is without the extension the cap tightens all the way home but as said when ext tube is fitted you can feel it clamping on the battery packs before quite screwing up tight, effectively this could over tighten the circuit board at the head of the torch if you were so minded and kept winching the cap on, take note this doesn't effect the sealing as the o ring is well covered by this point, basically the extention tube is 1mm too short. Apart from this its doing a great job

A great bit of kit and perfect to extend the running time of my TK75. The communication received from torch direct was excellent from ordering the part to getting it delivered. a truly customer first company.

Great booster for the TK75

Simple idea that works very well with the TK75 to extend its overall run time. Prompt despatch, great advice and information from TD - highly recommend this company.

Makes a great torch even better.

A quite simple idea, being able to add battery capacity when needed. By adding the extention, the duration is proportionately increased. It obiously adds to the weight, but the balance of the torch is still good. Excellent service, as always from Torch Direct.
