      My son has really enjoyed the boxes so far. Good experiments to keep him interested with just the correct amount of content. The fact it all fits through the letterbox is an added bonus.

      Letterbox Lab is a fantastic educational product. I Home educate my 10 yr old son and we receive a new investigate box every month. Everything you need is supplied in the box, so no need to rush out and buy extra ingredients. Both myself and my son look forward to our science sessions every week, in fact it’s the highlight of our week. Always arrives on time and it does what it says on the box ‘ fits straight through your letterbox’ so no need to worry if we aren’t in on delivery day. This really is the best educational product I have bought my son. Thankyou Letterbox Lab �

      We set up a 2 monthly subscription when we ordered our 1st box but when we received it our children loved it so much we have changed it to monthly, it's lots of fun and they wanted to do it all in one go! It was easy to understand and they loved that they could tick off bits in the book.

      This is an excellent Science kit and my 7 year old son absolutely loves it! It makes Science so much fun as it is learning by doing, not just looking at 2D worksheets. As a parent it is easy to be confident when everything is in the box ready to go and there are easy child friendly explanations for all the experiments. Would highly recommend!

“Extremely good value for money…we found it easy to put time aside to do an experiment every couple of days”

“I cannot recommend this subscription box enough. This isn’t only because of the actual product and the fun we have encountered, but also because of the people behind the product. The customer service we have experienced has been second to none,” 

Lorraine (It’s a Family Adventure)

“This box was aimed perfectly at Miss A’s age range. She was completely engrossed in the experiments throughout and can not wait for the next box to arrive! … “

“The box is great value for money…the quality and presentation excellent…build up your own Science kit.”  

Patricia (Four Little Girls… The Mummy Memoirs)

“The attention to detail is amazing and it has been put together in a very visually engaging way.”

“The first box contained a well designed instruction sheet and all of the equipment needed to do the experiments. And I mean everything!”

Alan (Here Come the Hoopers)

“These are really excellent kits that really do supply everything needed to get on with the fun”
