8 Reasons For

Low Running Costs

The EB-421i is one of the more economic to run multimedia projectors that have been around for more than a year that we have looked at for 1 year running costs. Based on average energy prices, we estimate the 1 year running cost of the EB-421i is only £97.

Epson Has Good Reviews for Its Data Projectors

Epson has good average reviews for its 3000:1 contrast ratio projectors as well as across its entire projector range compared to other manufacturers.

Supports Wi-Fi

The EB-421i supports wi-Fi, which is unusual. Most of the other projectors that were released more than a year ago do not support wi-Fi.

We compared this projector to all the other projectors with a wi-Fi and we think the Sony VPL-SX631[plb_3301602_price] is also worth considering.

Has a Built-In Speaker(s)

The Epson EB-421i has a built-in speaker(s), as do most of the other projectors of a similar spec and age to the EB-421i.

It is worth considering other projectors which also have a built-in speaker(s) including the VPL-SX226[pl_3301477_price], or the VPL-SX236[pl_3301501_price] both from Sony.

The weights of 3000:1 contrast ratio projectors that were released around the same time as the EB-421i range from 3.4kg to 6.7kg.

Multimedia projectors of a comparable spec and age to the EB-421i have noise level (economic mode)s of between 28dB and 36dB. With a noise level (economic mode) of only 28 decibels, the Epson EB-421i has a fairly quiet noise level (economic mode) compared to most of the other 3000:1 contrast ratio projectors that came out around the same time as the EB-421i.

7 Reasons Against

If you want a projector with a brighter projector brightness then you might want to look at the VPL-SX226[pl_3301477_price] (2,800 ANSI lumens), or the VPL-SX236[pl_3301501_price] (3,300 ANSI lumens) both from Sony.
