BB injector tool...worth it?

As Hodgy said, you wouldn't use it, it's maybe a once a year tool innit, the tools i use the most is my multi tool, which is basically allen keys, you can buy a case of tools for £40 ish and it's got all the essentials in it, other than that i'd take the bike to a shop and let the experts fix it, basic knowledge is good though

sounds like the perfect lubricating method.injecting clean grease and releasing contaminated grease. if your BB is going to be a permenant fitting it sounds like its worth considering. if you expect to have to replace it some time down the line then maybe not.as always its all swings and roundabouts, weighing up the cost of the bike and componants against the cost of the tool you're thinking of buying..............................................thats not much help is it? 
knowing that you are lubricating a componant properly yourself is worth alot as opposed to relying on joe bloggs the bike mechanic.
by the way, can you lubricate the BB with the injector while its in situ? or do you have to remove it from the bike to do it? that could be something else that helps you decide.

Thanks guys for the responses...some different ones!
Yeah...I believe it's within my capabilities and you don't have to remove it which is great I think! Movie below if you are bothered! Everything going well, I will keep this BB and this bike for many many years! I would think i would do it every 6 months at least.
i think any mechanic would charge at least 20 quid a time...like the cable issue I had, I realise no one will care about your bike as much as you...lol...it's the grease gun with the special "nozzle" that I need to find as well if I buy it since CRC etc don't seem to have it!

its just a standard grease gun with a standard nozzle

just something else im thinking. there could be a chance that its easy to pump too much grease into the bearings to the point of 'packing' it. the bearing might last for ever but might not run as freely because of too much grease in the bearing. that will also depend on the viscosity of the grease.

Greedy!? I will get the tool...and maybe at some stage you can give it a try.

There we go lol.

You're that good, you answer your own questions lol

Not sure ive youve bought it already but, the CK grease tool is worth getting if you have a CK BB and want to maintain it yourself.

Also the Evans guy was right the two plastic shims are to eliminate play if the BB housing is a little wider than the specced BB. Only played with one once an seen it used its a nifty idea but make sure you use a grease they approve guy I saw used TFR2 cant remember if its one of the approved ones of not. Usually you can use a standard gun with a hose to attach to the nipple on the CK unit bit like when you do brakes.

No problem, the CK BB tool is very over priced for what it is. Its just a standard 16 notch BB so you can pick those up for under a tenner

Worth having they work on most 44mm BBs. Plus You dont have to remove it but im sure youve seen when you remove an old BB the amount of crap that lurks between the cups in the dead space, also handy to regrease the treads to reduce the risk of it seizing if you have to replace whole BB.
