I’ll close this tab when the next thread comes out this Saturday :~)
I don’t have an answer because I don’t have any of those things but the way I shop for gadgets is to search amazon and not only go by how many stars in the ratings but read the reviews which will give more insight. Then I go find it somewhere else, often cheaper and sometimes direct from the company’s website. Sometimes I’ll find it on ebay and when I do that, I check the seller’s location and try to make sure the people in that area are likely conservative.
That’s usually my angle too, but, on these gadgets, like I said, the reviews are all over the place and no units or brand seem to stand out. None have a particularly high number of 5 star reviews, either, but the 5 star reviews are generally fairly detailed and convincing.
I may just buy one locally, perhaps the Lowes unit, and see if those tips really are all that fragile before I put it in the ground — and also not try to drive it into hard clay! That makes a return if needed more practical.
