## Product: Philips Surge Tap SPP3993W/37
**Brand:** Philips

## Pros
- Provides reliable surge protection with a solid 1140 joules rating, suitable for most appliance-grade needs.
- Practical and easy to use, with a nearly flat design that allows mounting a TV close to the wall without blocking outlets.
- Features a convenient bottom breaker switch for easy on/off access.
- Side outlets are adapter-spaced, helping prevent cords from bending and making plug access easier.
- Outlets grip plugs well, reducing accidental disconnections.
- Build quality feels generally solid and durable with a neat, presentable appearance when mounted.
- Single plug fits standard duplex outlets, helping to save space on the wall.

## Cons
- Clamping voltage is quite high (800V), which means it's better suited for appliance-grade protection rather than safeguarding sensitive electronics like computers or gaming consoles.
- The hold-down screw and wall screw included are often too long for some commercial or spec-grade outlets, requiring trimming before installation.
- Some users found the overall build quality lower than expected for a Philips product, with concerns about the materials used.
- The product did not meet expectations for certain users, who felt it was not suitable for their intended use.
- Installation can be a hassle due to the screw length issues, especially in tight or specialty outlet setups.

## Bottom Line

The Philips All-in-One Surge Tap offers a practical and durable solution for general appliance protection with a high joule rating and a smart space-saving design. However, if you need surge protection for sensitive electronics, the high clamping voltage may not provide optimal safety. Also, be prepared to modify the screws for installation in some outlet types. For those focused on electronics with delicate components, consider searching for surge protectors with a lower clamping voltage and higher joule rating tailored for sensitive devices.
