Durable and Safe Extension
This is the second time I have bought it. The picture I shared is of the one I bought 2 years back. *Wire - Durable, thick, safe, long enough (if someone needs a longer wire, then it's a problem) *Plug - good quality *Sockets - enough space between sockets for laptop and phone charger plugs, use OnePlus charger on the corner socket. No sparking issue in 2 years, button for every socket is very useful and is sturdy enough. LEDs are also fine quality. no issues observed yet. *Load - I have used this with 2 laptops and 2 super vooc chargers at same time. And also used it with coolers, table fans, iron. I recommend this for ironing purpose and other high load devices. I ordered it this time specially for my mom as it's safe to use with iron/press *Looks - who cares but you know what it looks much better and classy than I expected while seeing the photos. *Price - I used to buy 100rs extensions, so it seemed expensive but after 2 years of usage I am never going to buy those 100rs ones that were totally unsafe and break down every year.

Value for money
So I bought one of these to power my aquarium filters, lights and air pumps, and I must say that I am really really impressed. Pros: 1) The product is really sturdy, and it could take some unintentional abuse. 2) All the four sockets can also take square plugs, so you wouldn't need to use adapters. 3) The switches are like push buttons (with a lot of quality to boast), so it's easier to know the on/off state from whatever angle you are looking at, even when there is no power supply. 4) In addition, all sockets have LED indicators to tell the on/off state. This is apart from the main LED indicator that indicates the on/off state of the extension box. 5) 3 meter long extension wire, which I think is plenty to go with. 6) Hook to hang the extension box somewhere if need be. Cons: 1) White colour may not be appealing to some since it usually tends to fade away or get dirty with time. -- If you are okay with the colour, do not look elsewhere if a four point extension box is what you're looking for. Cannot go wrong with this product. PS: The product dimensions (24.5 x 8 x 3 cm) given in the description are accurate.

No doubt a quality product
The product is visually impressive as well as very good to use. The quality is top notch. The wire is of the said length and is nice thick with good insulation. the board is aesthetically pleasing too. The buttons are sturdy to operate and seem would last long. Go for it if you are looking for quality. It appears to be bit expensive is worth the money.

High quality extension board, the best
Excellent, high quality product. Supports high load appliances like washing machines without heating issues. Chord length of 3 meters is more than enough and made of thicker guage to last for a fairly long time. Sturdy, high quality materials used, feel and looks are good. This my 3rd purchase. Completely trust the brand. Just incomparable.

Safety First --- the best Polycarbonate Extension Board
First of all, I want to mention that BULL is the largest manufacturer of Extension board & is the leading brand in USA, Germany, France , United Kingdon & Japan. Pros: + It’s made of high quality Polycarbonate Plastic ensuring strength & High-temperature resistant. + It has integrated pure brass circuit ensures high conductivity. It’s the World’s first of its kind. No wiring inside (as found in other brands) + 100% pure brass bar inside fixture reduces risk of short-circuit to minimum. + It has three-core wiring of plug outside. + It works with all international plug types. Different standard of plugs can be used. + No loose plugs due to international sockets with “Lock-in” technology. + 4 international sockets with individual silver contact switches for lifelong usage & individual LED indicators also. Cons: - This does not have a circuit breaker (or fuse) for overload protection. ============================================================ Last but not least, BULL uses the most specialized material and technology to provide customers with a safe and comfortable environment for using electricity, thus improving life quality.

Nice. some thing nice LOOKING
Overall it is made and design fine with sleek and good looking. type of soft touch and good plastic is used possible it can be fire resistant plastic-type. The switches feel good making clicking sound on/off.. overall it is good same as like any other brand as In this price pool there are many other companies which offer the same thing and some are even inexpensive also but of Couse the design and soft-touch plastic the clear box give it a bit of up in the visual dependent
