2. Purpose: test spark plug performance and ignition strength
3. Application range: 12V gasoline engine automotive spark plugs
4. The dual-hole automotive spark plug tester has two test holes, which can test two spark plugs at the same time. If you suspect that any spark plug is not working properly, you can do a comparative test to make an accurate judgment
5. Test principle: In the automotive ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug leads it to form a high-voltage ignition coil into the cylinder engine. The spark between the spark plug electrodes ignites the mixture. The detector can distinguish good spark plugs from bad spark plugs according to the intensity of the spark

Disappointed
Color: Platypus - pineapple plush, Color: Platypus - pineapple plush
3 month old husky mix ripped this toy open within hours of having it and as of now, all the feet are missing. I only let him play with it a few hours a day because of the squeaker, so not as advertised.

Teething Puppy Destroyed Goose
Color: Blue goose - pineapple plush
Product appearance attractive and looks like fun, however, simply did NOT withstand an aggressive chewer like my 10 week old puppy - did not last more than three days and needed to be thrown out for safety reasons. ☹️

Not indestructible but she had fun tearing it apart.
Color: Blue goose - pineapple plush
Hardly indestructible as the description claimed. She enjoyed it, while it lasted, for 15 minutes. I wish I could figure out how to show the photo of her after she tore it up. But I can’t. Sadly.

It's one of the only toys that we originally got for our pup that has lasted
Color: Blue goose - pineapple plush
We got a lab mix (we think with a Great Dane) on Labor Day weekend 2025. She has destroyed 100% of the toys we got her that weekend, with the exception of this duck. Yes, it is missing it's feet at this point (they got chewed off and torn sometime around Halloween), but the duck itself is still intact. She chews on the duck every day, it's one of her favorite toys, and it's seen some things. We've washed it a few times in the laundry machine, and it looks nice a clean every time we pull it out and let it dry. She's gnawed on it through losing puppy teeth and getting adult teeth, and she's is currently chewing away on her duck on her bed in the living room.
I understand others have reported really mixed reviews, but I'm so glad we got this duck and it's one of the only toys we've bought that I feel like was worth the price because it didn't get destroyed immediately. We plan on buying another one for Christmas.
