Omg this mat is a lifesaver! I bought the one in the tan color and it looks so high end compared to those ugly plastic ones you get at the big box stores. Its super easy to wipe down which is the most important thing tbh because... well, babies lol. It folds up really small so it fits in my purse when I don't want to carry the whole diaper bag. Definitely worth the money.

I’ve been using the ANEX 395-DB2s for about two weeks now on a commercial rough-in and the double-headed design is actually way more convenient than I expected. They seat perfectly in my impact driver and the slim profile helps get into tight terminal blocks. Only downside is if you lose one it’s a bit of a bummer given the cost per bit, but honestly the durability makes up for it. Much better than the Wera bits I was using previously which tended to shatter under high torque.

I have really fine hair that breaks super easily so I'm picky about what I use. These are gentle and don't pull out half my head when I take them out at night. Worth the splurge if you care about hair health.

I have mixed feelings. On one hand, it's very convenient and the price was right. On the other hand, the battery cover is really flimsy and feels like it might snap off every time I change the 9V. It gets the job done but don't expect premium build quality. Just a basic plastic keypad.

Got the 2 pack for my front and back windows. The 2K resolution is legit sharp during the day. Def worth the money if you don't want to drill holes in your siding.
