In the past 3 weeks I bought 3 different chainsaws.  They were all returned.  
Chainsaw #1 required I have octopus arms to hold, level, tighten, adjust the chain, and find the tension screw with a flashlight in the fifth hand.  Chainsaw #2 had the chain flying off no matter how precise the chain was on. Chainsaw #3, I said, forget it and took it back without even opening the box.
I bought a canister of Metamucil.  Probably going to regret that, too.  It doesn't dissolve completely in cool/cold water, and you need to drink it right away. 
I thought I would add the Metamucil to a hot drink, but decided to see if that was a good idea.  Oh, no.  It will turn into a gel, so guess I will have to try and learn to drink faster.
