OK, best I've found on Amazon, not even close to T&B, but cheap.
These are "OK". not as good as Made in USA parts, but "OK". Better than other brands on Amazon, which are "Crap".

Worked on a vintage motorcyle.
I rebuilt 2 cable ends on a 1975 Norton Commando. Worked good and now I have extras.

Crimped well
crimped to 25mm2 cables (about #3) no cracked connectors. Med weight, but not 5 dollars each. would recommend for general use. Vender was fast.

Compartments in the case are far too small.
Not easily closed after opening due to the small compartments of each size . They cross over with the slightest movement if the lid is open. Now you will have to check each before use. Enlarge the compartments of the case and all is well

They Work Fine – But I Personally Prefer Bare Copper Lugs
They Work Fine – But I Personally Prefer Bare Copper Lugs I'd give these Wirefy tinned copper wire lugs a fair 3 stars. From a basic functionality standpoint they work as intended—the crimp barrel accepts 6 through 2 AWG wire properly, the ring terminals fit standard bolt sizes correctly, and the 30-piece kit covers a variety of gauge and ring size combinations for different battery and solar wiring applications. My hesitation is purely a personal preference issue—I prefer bare copper lugs over tinned copper for my specific wiring applications. While the tinned coating does offer corrosion resistance benefits, particularly in marine or moisture-prone environments, it affects the feel and behavior of the connection in ways that don't align with my preferences for the solar and 12V electrical builds I work on. If tinned copper lugs suit your application—especially marine, outdoor, or humid environment installations where corrosion protection is a priority—these will serve you well at a fair price for a 30-piece kit. But if bare copper is your preference like it is mine, it's worth seeking out an alternative option. They work, just not my first choice.

Cosses solides, excellente conductivité, kit très pratique
J’ai acheté ce lot de cosses rondes Wirefy pour raccorder des câbles de batterie et des masses, résultat impeccable. Le cuivre étamé inspire confiance, bonne conductivité, résistance à l’oxydation, parfait pour une installation durable. Les cosses sont bien formées, s’écrasent proprement avec une pince adaptée, maintien ferme une fois serties. Les différentes tailles permettent de couvrir plusieurs sections de câble, très pratique pour l’atelier ou l’auto. Produit de qualité, bien conditionné, excellent rapport qualité/prix pour ce type de consommable électrique. Je recommande sans hésiter.

Good quality
Surprising better than what I thought. They are sturdy, cheap and easy to crimp. Would and will buy again for the same price.
