(1) A Creative Labs Sound Blaster sound card I regretted buying years ago - because once connected, I realized (A) the drivers sucked and (B) the on-board sound was just as good through my THX certified, self powered surround sound speakers. I should have gone with my original, but more expensive choice, the
M-Audio Revolution 5.1, which I ended up buying (and appreciating) anyway. Lesson learned: Do better homework before buying and stop being a tightwad.
(2) A $12 RJ-45 Ethernet connector crimping tool - a piece of junk. Lesson learned: Don't buy junk tools and stop being a tightwad.
(3) A $24 RJ-45 Ethernet connector crimping tool - a more expensive piece of junk. Lesson learned: More expensive junk tools are still junk. To save money in the long run, buy quality tools from the start. And stop being a tightwad.
(4) Two Corsair Carbide 300r cases - quality design, inconsistent manufacturing techniques and poor and inconsistent quality assurance (QA). One case still had rough, unfinished edges on the sheet metal resulting in shredded and bloody knuckles. Both cases were un-"true". That is, they did not have exactly 90° bends in the sheet metal. This resulted in the cases sitting on only 3 of their 4 feet allowing them to wobble. It also meant the side panels were extremely difficult to remove and replace due to improper fit. Note two other identical 300r cases were just fine (hence the inconsistent QA complaint). Lesson learned: Don't assume a company known for making quality power supplies also makes other products of similar quality. (Note: this was before Corsair changed PSU OEMs).
(5)
Acoustic Research Outdoor Bluetooth Speaker - For $28 I was NOT in any way expecting anything close to high fidelity audio. I just wanted something a little better than the 40 year old Realistic (yes, from Radio Shack) mini "boom box" I had out in my shed for when I was putzing around the yard. I do not like wearing earbuds when all sweaty and grimy. I figured with the AR brand on it, even at that price, it could not be that bad. I was wrong. I have heard 60 year old "transistor
AM radios" sound better. Lesson learned: Hire someone else to do the yard work.
