Durable Padlock – Built to Last and at a Reasonable Price
I’m impressed with this Master Lock padlock. It feels solid and durable, the thermoplastic cover protects the body, the key works smoothly every time and gives confidence that your items are secure. Laminated steel construction and a protective cover make it resistant to rust and scratches. Great for securing gates, lockers, or storage boxes, and it’s easy to carry around. Overall: A reliable, high-quality padlock that does its job flawlessly. Pros: Strong construction, scratch/weather-resistant, easy to use Cons: Heavier than some lightweight alternatives. Verdict: Tough, dependable, and excellent value for securing your belongings.

Good value for a basic low-security lock
This is rated 5/10 on the ERA scale, meaning a mid-range level of security equivalent to 3/6 on the BS EN 12320 Security Grade. It feels well made and is heavy in the hand. The weatherproofing is thick, although has a slight flaw in its design - the rubber around the shackle is flanged (good) in that it meets the body, however the top of the body itself is covered in a very flexible rubber without a hard surface underneath it (see second photo), meaning that it simply pushes away from the shackle rather than forming a tight seal. Its an odd oversight. The clip-in plug for the keyhole is really well designed in contrast, and clips firmly and securely into place. However unless the lock is being used inverted, this merely means that the lock is better waterproofed at the bottom than the top, which will simply trap any water in the lock and prevent it from draining. The lock mechanism is OK, probably acceptable for this price point. The lock is reasonable protection against casual theft/breaking attempts but is not with its 5/10 ERA security rating means that it has no rating or guarantee against either drilling or sawing, so could likely be cut through in seconds with a portable handheld angle grinder. I'd say for the price this is great value for use in low-risk areas such as indoor lockers or cabinets in rooms secured against external entry. I would not rely on it in any more critical environments.

Review of the Master Lock
This is a great product that delivers exactly as expected. The lock is of good quality and easy to open. It seems resistant to rust thanks to its durable plastic coating. Additionally, it features a waterproof lock cover that helps minimize the risk of rust. It comes with two keys, which function perfectly. The packaging is also easy to open; despite being a plastic blister pack, I was able to open it without scissors. As someone with only one fully functioning hand, I found it simple to open the packaging and use the padlock without any trouble.

Disappointed for Outdoor Use — Rust Issues After 1.5 Years
I specifically ordered this padlock for outdoor use, thinking it would withstand the elements, and I really wanted to use it outside. Unfortunately, after about a year and a half, I’m already seeing rust forming at the keyhole. It’s still technically usable, but now it’s getting much harder to operate with the key, which is frustrating. The plastic coating on the lock is not fully waterproof — water seems to get in somewhere, which is likely what’s causing the rust. I really hoped it would hold up better, especially for outdoor conditions, but it looks like it won’t last much longer if the rust keeps spreading. If you need a padlock for outdoor use, I’d be cautious — this one isn’t as weatherproof as advertised.

Master Lock 7804EURD: Decent Basic Security
Pros: * Weatherproof: Thermoplastic cover offers good protection against rain, dirt, and grime, making it suitable for outdoor use. * Solid Build: Laminated steel body feels reasonably sturdy for its price point. * Decent Security: Features a 4-pin cylinder which offers some resistance to picking. * Good Value: Generally considered an affordable option for basic security needs. * Two Keys Included: Provides a spare, which is always useful. Cons: * Not High Security: More determined thieves with specialized tools could likely bypass it. * Potential for Rust (Long Term): While the cover helps, some users have reported rust issues over extended periods, particularly if the cover is damaged. * Keyway Cover Can Be Fiddly: The snap-on keyway cover, while protective, can sometimes be difficult to remove, especially with gloves or limited dexterity. * May Stiffen Over Time: Some users have experienced the locking mechanism becoming stiff with prolonged use, especially outdoors. Overall: The Master Lock 7804EURD is a decent, budget-friendly padlock suitable for general, low-to-medium security applications like securing sheds, gates, or storage boxes. The weatherproof cover is a definite plus. However, it's not designed for high-value items and may have some longevity issues in harsh outdoor conditions. Consider your security needs carefully before purchasing. Review 01/01/2026 The Master Lock 7804EURD is marketed as a "Weather Tough" solution, but real-world performance in wet climates is disappointing. While the thermoplastic cover looks protective, it often serves as a trap for moisture, leading to significant internal rusting after just one winter. The laminated steel core is highly susceptible to corrosion once moisture bypasses the outer shell. Only use this for indoor low-security needs or very temporary outdoor use in dry regions.
