Hi Helen, thank you for your review and feedback. Great to hear you are a fan of the Hoselink products you have and have always found them to be great quality.
Sorry the sprinkler is not covering the area you expected, this sprinkler should do around a 6metre diametre therefore, it is not a huge area but great for small blocks.
Of course, if you would like to figure out which options would be best, we would be more than happy to help!
Kind regards, The Hoselink Team
