  8. Did the job. 4 Star Review

    Posted by on 19th Nov 2014

    Rubber screw in feet provided on range cooker had disintegrated after only 7 years and needed replaced. These feet MAY have been easier to slide when pulling cooker out for cleaning but I decided to buy a set of heavy duty rollers as well. I haven't tried adjusting the feet individually because I have no need to at the moment but they will be easily adjusted if required.

------------------------------------- The castor was perfect for our needs, to replace a broken one and use an existing stem which couldn't be removed. So many castors nowadays come with a stem which can't be removed. Customer services and delivery were flawless. We'll use this company again, well done to them. Adriana Williams
------------------------------------- As a domestic customer, it was quite a work-up trying to find replacement domed inserts for our dining chairs. Like so much furniture these days, our chair were made in China. Great design, but trying to get replacement feet was proving a nightmare. After much searching on the web, thankfully we found 'castors unlimited'. They were very helpful. Cannot recommend highly enough. Oh, the product, Good quality,made in Britain. What more could we ask for! John.
------------------------------------- Small problem with packaging, (may have been caused by Royal Mail handling). Contacted Castors Unlimited, resolved, replacement missing part received and fitted all within 24 hours. Well done Natalie and team. These were for IKEA Markus chair, perfect fit and much smoother action. Mr Donovan
------------------------------------- I purchased M10 adjustable glides. The service and price where both excellant. Regards. John Pears Rollaco Presses.
------------------------------------- I just wanted to let you know I am really pleased with the product, price and speed of service from you. E-mail notifications were really good as well. I do a lot of purchasing for work and I'm used to companies not doing what they say they will so it was really nice to have an efficient service from yourselves. Keep up the good work! - Thanks a lot, Reece Gale
------------------------------------- Several companies seemed to be viable contenders to supply what I needed, but Castors Unlimited had by far the most impressive website. So I just measured my broken castor and filled in the online form - two days later my problem was solved. I actually bought two because I never know if anopther castor might collapse (the chair is about ten years old!) and they are so inexpensive that it seemed silly not to.

Their products are of excellent quality and competitively priced. Customer service is second to none, especially when we require items the next day!

------------------------------------- Happy New year and my apologies for taking so long to get back to you. With regards to both your service and the product that I ordered for the school, I would like to say I was very impressed with your assistance in getting the right item. No doubt I will be in contact with you as and when we need more items! Many thanks Ian Betts, Blessed William Howard Catholic High School.
------------------------------------- Castors Unlimited are certainly competitive, I have had a good Google around, but price isn't everything as service is very important too. Whilst one is able to see prices online there is little indication on how good the service may be. CU have proven on both counts so I have little intention of going anywhere else. Thank you for that. - Andy Young

As a result of a broken castor on my office chair, I was told to speak to these people. Very helpful and knowledgeable staff, who helped me with the size and type of castor required, which can be tricky. Product delivered within a couple of days of order and my office chair is as good as new and at a fraction of the cost of buying a new one. Thanks!Posted By: Roger.
"wheelie" good casters by Martin (Southgate N14) on 22nd Jun 2013 Good quality replacements for my 'home' office chair at what I regard as modest prices. The advice received as to the exact product was spot on and delivery very prompt. Well done!
