  1. Too much hassle for a measly three year warranty. I own Bosch makita Milwaukee dewalt tools which I still use older than 20 years. I suppose if I knew that I was going to put a tool thru the grinder and not take care of it, then I would go thru the trouble.

  2. I keep my receipt until the warranty runs out. Here in canada there's a tool store named KMS tools they are a certified warranty dealer for alot of tool brands. They also give a one year extended warranty with a small deductible

  3. Your videos help a lot with home diagnostics and maintenance, but as most of my tools are cheap(er) "semi-professional" models (plenty good enough for my hobby use) I won't bother with any serious repairs. Professionally I'm a medical doctor, so it's more sensible for me to simply replace a faulty tool than spend hours repairing it even if I'm pretty confident that I could. I'm not wasting the old tools though, I give them to a hard working young man who's struggling to provide for his growing family, he's able to fix most of them and make a few bucks.

  4. Bosch are probably getting a lot of these back under the extended three warranty and so you would expect that they move away from sintered metal for those gears that come in for a lot of abuse.

  5. In places like Australia and New Zealand the extended warranty is 6 years even on batteries. The easiest way to register is to use the app, you just scan the QR code then it asks for a photo of the receipt, done. It's all one account now as well across Bosch so you can use the same account you use for you appliances.

  6. I always registered my tools for extend ded warranty.

    But it really creams my corn how we have to jump through all these hoops & hurdles juts to get something that we should have as standard anyways & is still worse than what they get in the US as standard.

    Milwaukee give 5yrs warranty in three US but here in three UK some of there tools are only 12 months regardless of registrationike this utterly shut 18v gasless 18g pin gun.

    Build quality of Milwaukee is shit especially their electronics, over half my tools had warranty repairs & I really look after my tools.

  7. I love how Dean gives us top tips like make sure you put this back in etc ….. there’s more chance of me walking on the moon than there is of me being able to reassemble anything like this πŸ˜‚πŸ˜‚πŸ˜‚πŸ˜‚

  9. and thats why it is important to register for 3 years waranty.
    bad seller dont inform about it
    good seller mention that there is that oportunity
    best seller himself fill 3 year waranty
    4 weeks to fill waranty but there is lots who dont do it and it cost sometimes a lot

  10. When I first started watching your channel I thought you had a very nonchalant way of removing parts, throwing them out of your way almost randomly. The more hours I have spent watching you, the more I see how efficient and controlled you operate. A non-expert would keep meticulously track of all the bolts and screws and the order of disassembly. Is there a method to the madness? I also was wondering how you started disassembling, perhaps very different then now, after so many thousand and thousands of repairs. Thank you Dean for your hard work, I am learning a lot from watching your channel.

  11. What a treat!

    My old Bosch breaker is 30 yrs old,with new sintered metal gear technology…. prefer to repair certain older tooling.
    The older tools were built for longevity ,however sometimes lacking in function.
    Newer tools are the reverse.
    I prefer a mix of both.
