'Features' - Singular or Plural

[edmondng]

I have a question on the use of the word 'features'.

Should the word 'feature' or 'features' be used for the following sentence, or are both acceptable?

--
The first products in the market which features a technology that reduces power consumption and produces lesser heat, the device ...
--

My opinion is, both are correct, depending on whether 'the first products' refers to a group where the word 'features' will be acceptable, or when used as multiple 'products', the word 'feature' may be used.

Your expert advice on this is greatly appreciated.

It looks as though there is a typo - "The first products" seems to link to "the device", which would indicate it should have been "The first product". If this is so, then "features" is correct.

In this case, the 'first products' refers to a product within a series, as in 'among the first products', but this phrase is not used because it sounds like other products in the market are also available, thus the reason for this question on whether 'The first products which features ...' is acceptable.

Thanks.

If it is essential to use "first products", then you must use "feature".

However, that leads to a sentence with poor internal logic.
